This book was released on 2015-10-13 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spinel ferrite thin films are promising candidates for high frequency applications due to their remarkable electrical and magnetic properties. Cobalt ferrite thin films have gained widespread interests in the applications of magneto-optical recording due to their large perpendicular magneto-crystalline anisotropy. The addition of non-magnetic Cr3+ ions could produce sufficient changes in the structure of cobalt ferrite. In order to achieve homogeneous cobalt chromium ferrite (CoCr0.5Fe1.7O4) thin films, various techniques such as electron beam evaporation, pulsed laser deposition (PLD), sol-gel, dip coating and spray pyrolysis have been developed. The deposition of CoCr0.5Fe1.7O4 thin films by electron beam evaporation technique is the focus of this book. This book also covers the effect of annealing temperature on structural, surface morphological, magnetic and optical properties of cobalt chromium ferrite thin films. It is noted that Ms and Hc increases with annealing temperature. Band gap energy and optical constants (n, k, ) decreases and increases with temperature indicative of good quality of thin films. So, the contents of this book will be helpful for the new researchers."

Available in PDF, EPUB and Kindle. Book excerpt: Data is of great importance to man and needs to be stored reliably such that it can be called upon and used at any time. Man has progressed over the years from relying on the brain as a data storage system to magnetic recording systems. Magnetic data storage consists of non-volatile memories (longitudinal or perpendicular recording media) where the information is stored. The perpendicular recording system has become the popular choice in recent times due to its ultra-high storage capacity. n this work we study magnetic thin film of Cobalt ferrite with in-plane and out-of-plane anisotropies as longitudinal and perpendicular media respectively. Different types of magnetic characterization were performed on the samples of interest through VSM and torque measurements. This study shows that films with perpendicular anisotropy are more magnetically stable than those with in-plane anisotropy due to their slow magnetic relaxation. The slow relaxation process is promoted through the demagnetizing field induced by the measurement geometry, which considerably reduces the irreversible magnetic susceptibility making perpendicular recording more suited for magnetic data storage. -- Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: The Co/Pd and Co/Pd artificial lattice films have attracted much interest by their special magnetization properties. We discussed the effect of the Pt, Pd layer thickness on the magnetic anisotropy, and we showed the effect of the hydrogen ion implantation on the magnetic properties of multi-layered films. The Co/Pt and Co/Pd multi-layered films were formed on Si(111) substrates with molecular beam epitaxy. We did structure analysis, magnetic domain analysis and magnetic properties evaluation with XRD, MFM and VSM, respectively. Among the series of films of 0.4 nm Co layer, XRD showed that the film of 1.0 nm Pt layer had a highest periodicity and that they had (111) plane orientation completely. The magnetic domain size reduced with the increase of the thickness of Pt layer. We found out that the coercivity decreased linearly as a function of the length of magnetic domain wall in the unit area. The result of VSM showed that the multi-layered films of Pt thickness of less than 2.8 nm had perpendicular magnetic anisotropy. The perpendicular anisotropy energy changed by the nonmagnetic layer thickness and had a maximum value for 0.4 nm Co 0.4 nm/nonmagnetic metal 1.0 nm multi-layered film. After hydrogen implantation into the films, XRD showed that the lattice spacing was swelled with hydrogen dose. Also, MFM observed that the magnetic domain size reduced with the increase of the hydrogen dose. The easy axis of magnetization changed from perpendicular to parallel in the plane with the increase of the hydrogen dose. After evacuation of hydrogen at 473 K, perpendicular anisotropy was partially recovered. This phenomenon suggested that the origin of magnetic anisotropy was mainly the lattice mismatch and distortion in the layer interface. But Co/Pd film was not recovered by this thermal treatment. This means that Pd made stable hydride and did not evacuate hydrogen at this temperature.

Download or read book Springer Handbook of Metrology and Testing written by Horst Czichos and published by Springer Science & Business Media. This book was released on 2011-07-22 with total page 1244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Springer Handbook of Metrology and Testing presents the principles of Metrology – the science of measurement – and the methods and techniques of Testing – determining the characteristics of a given product – as they apply to chemical and microstructural analysis, and to the measurement and testing of materials properties and performance, including modelling and simulation. The principal motivation for this Handbook stems from the increasing demands of technology for measurement results that can be used globally. Measurements within a local laboratory or manufacturing facility must be able to be reproduced accurately anywhere in the world. The book integrates knowledge from basic sciences and engineering disciplines, compiled by experts from internationally known metrology and testing institutions, and academe, as well as from industry, and conformity-assessment and accreditation bodies. The Commission of the European Union has expressed this as there is no science without measurements, no quality without testing, and no global markets without standards.
