Evolution of microstructure and magnetic properties in magnetron-sputtered CoCr thin films
Ranking is calculated from a formula comprised of user reviews and usage data. Learn more ›
02 Feb 2012 | Publications | Contributor(s): Brian Demczyk
In this work, transmission electron microscopy, including the Lorentz mode is combined with magnetic measurements (vibrating sample magnetometry and ferromagnetic resonance)to draw correlations …
Growth of Cu films on hydrogen terminated Si(lQ0) and Si(lll) surf&es
07 Oct 2011 | Publications | Contributor(s): Brian Demczyk
We have employed reflection high energy electron diffraction (RHEED) and high resolution transmission electron microscopy (HREM) to study Cu films grown on hydrogen terminated Si( 100) and Si( 111) …
Interface structure and surface morphology of (Co, Fe, Ni)/Cu/Si(100) thin films
We have examined bilayer Co/Cu, Fe/Cu, and Ni/Cu films deposited by molecular-beam epitaxy on hydrogen-terminated @100# silicon substrates. Coauthors: V.M. Naik, A. Lukaszew, R. Naik, G. W. Auner
Origin of the orientation ratio in sputtered longitudinal media
The surface morphology, thin film microstructure, and crystallography of sputtered longitudinal media were examined by atomic force and transmission electron microscopy. Coauthors: J. N. Zhou, G. …
Magnetic properties of magnetron sputtered Co-Cr thin films
The magnetic properties 01 magnetron sputtered CO-22 at.% Cr films of various thickness deposited on glass have been examined, with particular attention to the various contributions to the film …
Oxidation Behavior of CoCr Thin Films
In this work, elemental redistribution of annealed CoCr thin films has been investigated by X-ray photoelectron spectroscopy.
Comparison of strain relaxation in epitaxial Si0.3Ge0.7 films grown on Si(001) and Ge(001)
Surface and interfacial strain have been computed for SiGe thin films grown by UHVCVD,based on measurements via transmission electron microscopy and Raman spectroscopy.
Lubrication Effects on Head-Disk Spacing Loss
The effects of lubrication thickness on the magnetic recording head-media tribology were investigated in this study.
Anisotropic magnetoresistance in colossal magnetoresistive La1-xSrxMnO3 thin films
03 Sep 2010 | Publications | Contributor(s): Jeng-Bang (Tony) Yau
We report on magnetic field and temperature dependent measurements of the anisotropic magnetoresistance (AMR) in epitaxial La1-xSrxMnO3 (LSMO) thin flms. While in 3d ferromagnetic alloys increasing …
Functional Graded Materials architectures applied at nanoscale: thin PVD nanograded and layered coatings
09 Oct 2008 | Publications | Contributor(s): Vasco Teixeira
Functionally graded materials (FGM’s) are designed to achieve levels of performance superior to that of homogeneous materials by combining the desirable properties of each constituent phase. …
