Download or read book The Detection of Weak Magnetic Fields Using Dipole Resonance in Thin-permalloy Films written by Carroll Eldrid Frank and published by . This book was released on 1965 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anisotropic magnetic thin films can be formed by vacuum evaporation and deposition of ferromagnetic materials in a dc magnetic field parallel to the substrate. Such films, especially those of nickel-iron of permalloy composition, were extensively studied, primarily with respect to properties useful in digital computer applications. Interest in those devices has developed for detecting very weak magnetic fields, using low-frequency-switching methods as described by West, Odom, Rice, and Penn. The work reported uses a new ultra-high-frequency magnetic-spinresonance method devised by the author. Among new results obtained are analytical and experimental verifications of the high sensitivity attainable. Although the actual sensitivities measured in ordinary laboratory surroundings were limited to approximately ten microgauss by the ambient magnetic noise level, the system is capable of much greater sensitivity if used in quieter locations.

Download or read book Ultra-Low Field Nuclear Magnetic Resonance written by Robert Kraus Jr. and published by Oxford University Press. This book was released on 2014-02-26 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed to introduce the reader to the field of NMR/MRI at very low magnetic fields, from milli-Tesla to micro-Tesla, the ultra-low field (ULF) regime. The book is focused on applications to imaging the human brain, and hardware methods primarily based upon pre-polarization methods and SQUID-based detection. The goal of the text is to provide insight and tools for the reader to better understand what applications are best served by ULF NMR/MRI approaches. A discussion of the hardware challenges, such as shielding, operation of SQUID sensors in a dynamic field environment, and pulsed magnetic field generation are presented. One goal of the text is to provide the reader a framework of understanding the approaches to estimation and mitigation of low signal-to-noise and long imaging time, which are the main challenges. Special attention is paid to the combination of MEG and ULF MRI, and the benefits and challenges presented by trying to accomplish both with the same hardware. The book discusses the origin of unique relaxation contrast at ULF, and special considerations for image artifacts and how to correct them (i.e. concomitant gradients, ghost artifacts). A general discussion of MRI, with special consideration to the challenges of imaging at ULF and unique opportunities in pulse sequences, is presented. The book also presents an overview of some of the primary applications of ULF NMR/MRI being pursued.

Download or read book Advances in Superconductivity III written by Koji Kajimura and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery of high temperature superconductors, many new materials have been invented. In the last year, several new materials were also discovered, but their critical temperatures are still below lOOK. Precise physical and chemical work has made tremendous progress in the theoretical and experimental study of physical properties and carrier state characterizations. The de Haas van Alphen effect measurement showed the existence of a Fermi surface in YBCO. Flux dynamics is a well-known new problem in which flux creep and irreversibility line features are especially important for a fundamental understanding of the critical current and flux pinning. Flux pinning centers which are intentionally added using non-superconducting precipitates, neutrons, and protons, etc. increase critical currents to practical levels. The analysis of electric and magnetic properties are expected to reveal the pinning mechanism and also to further application development. As for wires and bulks, many melt-like sintering techniques have improved the material performance of critical current densities. A new seeding Quench-Melt Growth technique enlarged crystal size and increased the repulsion force. These melting processes, in conjunction with a mechanical strength improvement have been effectively introduced into wire fabrication in order to realize kilometer range wires and will put the oxide wires to practical use. Where thin film is con cerned, when many fabrication methods had been developed using the assistance effect of activated oxygen such as ozone and oxygen radicals, a high current 2 density of 106A/cm at 77K was reported.
