Magnetization Reversal and Nanoscopic Magnetic Phase Separation in Doped La1-xSrxCoO3
Joseph E. Davies, J. Wu, C. Leighton +1
The doped perovskite cobaltite La1-xSrxCoO3 (LSCO) has been advanced as a model system for studying intrinsic magnetic phase separation. We have employed a first-order reversal cur…
Angular dependence of the magnetization reversal in exchange biased Fe/MnF2
Elke Arenholz, Kai Liu
A detailed study of exchange-biased Fe/MnF2 bilayers using magneto-optical Kerr Effect shows that the magnetization reversal occurs almost fully through domain wall nucleation and…
Anisotropy Dependence of Irreversible Switching in Fe/SmCo and FeNi/FePt Exchange Spring Magnet Films
Joseph E. Davies, Olav Hellwig, Eric E. Fullerton +4
Magnetization reversal in exchange-spring magnet films has been investigated by a First Order Reversal Curve (FORC) technique and vector magnetometry. In Fe/epitaxial-SmCo films, t…
Loop Bifurcation and Magnetization Rotation in Exchange Biased Ni/FeF2
Justin Olamit, Elke Arenholz, Zhi-Pan Li +6
Exchange biased Ni/ FeF2 films have been investigated using vector coil vibrating sample magnetometry as a function of the cooling field strength H_FC. In films with epitaxial FeF2…
Reversal-field memory in magnetic hysteresis
H. G. Katzgraber, F. Pazmandi, C. R. Pike +4
We report results demonstrating a singularity in the hysteresis of magnetic materials, the reversal-field memory effect. This effect creates a nonanalyticity in the magnetization c…
Reversal-Field Memory in the Hysteresis of Spin Glasses
H. G. Katzgraber, F. Pazmandi, C. R. Pike +4
We report a novel singularity in the hysteresis of spin glasses, the reversal-field memory effect, which creates a non-analyticity in the magnetization curves at a particular point…
