Ferroelectric Domain Motion
07 May 2018 | Contributor(s):: Brian Demczyk
Videos show total ferroelectric domain disappearance in bulk La-doped lead titanate, and incomplete reversal in a small (< 0.5 micrometer) grain, when heated through the Curie point.
Magnetic Domain Reversal
Videos show magnetic domain disappearance and reappearance in a Co-22% Ct thin film when heated/cooled through the Curie Point.
Interface Structure/Surface Morphology of (Co,Fe,Ni)/Cu/Si Thin Films
25 Mar 2014 | | Contributor(s):: Brian Demczyk, R. Naik, A. Lukaszew, G. W. Auner, V. M. Naik
The effects of thin film and interfacial stress on the magnetic properties Fe, Co and Ni films deposited by molecular beam epitaxy on Cu underlayers (Si substrate) were examined, employing transmission,ans scanning probe microscopy and reflection high energy diffraction. It ws found that the...
Evolution of Microstructure and Magnetic Properties in CoCr Thin Films
25 Mar 2014 | | Contributor(s):: Brian Demczyk, J. O. Artman
This presentation describes the structural and magnetic properties, including domain structures, in magnetron-sputtered Co-25% Cr thin films.
Evolution of microstructure and magnetic properties in magnetron-sputtered CoCr thin films
02 Feb 2012 | | 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 between the structural and magnetic constituents in cobalt-chromium films of increasing thickness.
