Rotational hysteresis of the exchange anisotropy direction in Co/FeMn thin films
Justin Olamit, Kai Liu
We have investigated the effects of rotating an applied field on the exchange anisotropy in Co/FeMn thin films. When the applied field is initially along the cooling field directio…
Asymmetric Reversal in Inhomogeneous Magnetic Heterostructures
Zhi-Pan Li, Oleg Petracic, Rafael Morales +4
Asymmetric magnetization reversal is an unusual phenomenon in antiferromagnet / ferromagnet (AF/FM) exchange biased bilayers. We investigated this phenomenon in a simple model syst…
Angular Dependence of Exchange Anisotropy on Cooling Field in FM/Fluoride Thin Films
Justin Olamit, Zhi-Pan Li, Ivan K. Schuller +1
Exchange anisotropy in ferromagnet/antiferromagnet (FM/AF) films is usually introduced along the cooling field or FM magnetization direction. Here we investigate the dependence of…
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…
Growth Mechanisms and Oxidation-Resistance of Gold-Coated Iron Nanoparticles
Sung-Jin Cho, Juan-Carlos Idrobo, Justin Olamit +3
We report the chemical synthesis of Fe-core/Au-shell nanoparticles by a reverse micelle method, and the investigation of their growth mechanisms and oxidation-resistant characteris…
