Download or read book A spin- and momentum-resolved photoemission study of strong electron correlation in Co/Cu(001) written by Martin Ellguth and published by Logos Verlag Berlin GmbH. This book was released on 2015-06-15 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electron correlation is an important phenomenon of solid-state physics, which is actively studied both by experimentalists for the rich material properties which result from it and by theoreticians which face a lot of open questions on the way to a succesful many-body description of electron systems where the Coulomb interaction plays an important role. Ferromagnetic cobalt is an interesting candidate for the study of electron correlation, since the exchange interaction splits the band structure into majority-spin and minority-spin bands, which differ considerably in the strength of the electron-electron interaction.Using a revolutionary, parallelized approach to spin-resolved photoemission with an efficiency 3 to 4 orders of magnitude higher than previously possible, the spin-dependent manifestations of the electron correlation are revealed in unprecedented detail, allowing for a characterization of the self energy. As an additional phenomenon of the electron correlation, unusual waterfall features, previously only observed in superconductors, occur in the photoemission spectra of cobalt. Further subjects include a comprehensive mapping of the fcc cobalt Fermi surface and an investigation of unoccupied quantum well states in ultrathin cobalt films on copper accessed by spin-resolved, non-linear photoemission. The principle of the imaging spin filter and the data analysis routine are discussed in-depth in a dedicated chapter.
Book Synopsis Colossal Magnetoresistive Manganites by : Tapan Chatterji
Download or read book Colossal Magnetoresistive Manganites written by Tapan Chatterji and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: The physics of transition metal oxides has become a central topic of interest to condensed-matter scientists ever since high temperature superconductivity was discovered in hole-doped cuprates with perovskite-like structures. Although the renewed interest in hole-doped perovskite manganites following the discovery of their colossal magnetoresistance (CMR) properties, began in 1993 about a decade after the discovery of high temperature superconductivity, their first investigation started as early as 1950 and basic theoretical ideas were developed during 1951-1960. Experience in sample preparation and characterization, and in growth of single crystals and epitaxial thin films, gained during the research on high temperature superconductors, and the development of theoretical tools, were very efficiently used in research on CMR manganites. In early nineties it appeared to many condensed matter physicists that although the problem of high temperature superconductivity is a difficult one to solve, a quantitative understanding of CMR phenomena might be well within reach. This book is intended to be an account of the latest developments in the phys ics of CMR manganites. When I planned this book back in 2000, I thought that research on the physics of CMR manganites would be more or less consolidated by the time this would be published. I was obviously very optimistic indeed. We are now in 2003 and we still do not have a quantitative understanding of the central CMR effect. Meanwhile the field has expanded. It is still a very active field of research on both the experimental and theoretical fronts.
Book Synopsis Ordering Phenomena in Rare-Earth Nickelate Heterostructures by : Matthias Hepting
Download or read book Ordering Phenomena in Rare-Earth Nickelate Heterostructures written by Matthias Hepting and published by Springer. This book was released on 2017-06-28 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents an experimental study of ordering phenomena in rare-earth nickelate-based heterostructures by means of inelastic Raman light scattering and elastic resonant x-ray scattering (RXS). Further, it demonstrates that the amplitude ratio of magnetic moments at neighboring nickel sites can be accurately determined by RXS in combination with a correlated double cluster model, and controlled experimentally through structural pinning of the oxygen positions in the crystal lattice. The two key outcomes of the thesis are: (a) demonstrating full control over the charge/bond and spin order parameters in specifically designed praseodymium nickelate heterostructures and observation of a novel spin density wave phase in absence of the charge/bond order parameter, which confirms theoretical predictions of a spin density wave phase driven by spatial confinement of the conduction electrons; and (b) assessing the thickness-induced crossover between collinear and non-collinear spin structures in neodymium nickelate slabs, which is correctly predicted by drawing on density functional theory.
Book Synopsis High-Tc Superconductivity by : Nie Luo
Download or read book High-Tc Superconductivity written by Nie Luo and published by CRC Press. This book was released on 2021-02-25 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: The exciton mechanism of high-Tc superconductivity in copper oxides was initially proposed by Prof. J. Bardeen. His insight is largely shared by another luminary in superconductivity, Prof. V. L. Ginzburg. The main author of the book, Dr. Nie Luo, was motivated by their insights to give a geometrical explanation to the excitonic Coulomb interaction and has developed a unique formalism to understand and predict physical properties of high-Tc superconductors. This work is supported by increasingly strong evidence for electron–hole interactions in p-type cuprates. The presence of electrons in hole-doped cuprates is revealed by the works of the authors and many others, including the late Prof. L. P. Gor’kov. The book also tries to understand the interlayer Coulomb (ILC) pairing model by the excitonic Coulomb interaction. Developed by Prof. A. J. Leggett, ILC theory shares many views with Ginzburg’s approach. The other author of the book, Prof. George H. Miley, shares with us his personal experience with Prof. Bardeen on the exciton’s role in physics problems including high-Tc superconductivity. The results and predictions of this excitonic Coulomb mechanism have been verified by an increasing number of experiments. This book summarizes the current status and fathoms future directions.

Download or read book Proceedings of the 11th International Conference on Vacuum Ultraviolet Radiation Physics written by T. Miyahara and published by Elsevier. This book was released on 2012-12-02 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: These volumes contain 365 of the 505 papers presented at the VUV-11 Conference, held at Rikkyo University, Tokyo, from August 27th to September 1st 1995. The papers are divided into three sections: atomic and molecular spectroscopy, solid state spectroscopy and instrumentation and technological applications. New aspects presented were both quantitative and qualitative improvements in fluorescence spectroscopy and magnetic circular dichroism measurements. The fluorescence data are complementary to those of photoemission in a sense but they appear to open up a new method to analyze the optical excitation and relaxation processes. The application of magnetic circular dichroism has proved to be useful not only in analyzing the electronic structures of magnetic materials but also in practical applications to material engineering as found in experiments combined with photoelectron microscopy. Excellent developments in applications are only found in the field of surface photochemistry, where the technique of etching using VUV light has been appreciably refined. Although the majority of distinctive scientific features in the VUV-11 Conference have been brought about by the application of synchrotron radiation, experiments using a different type of light source appear to have progressed steadily. This is evident in the studies of plasma radiation.
