Dynamic Spin-Polarized Resonant Tunneling in Magnetic Tunnel Junctions
Casey W. Miller, Zhi-Pan Li, Ivan K. Schuller +3
Precisely engineered tunnel junctions exhibit a long sought effect that occurs when the energy of the electron is comparable to the potential energy of the tunneling barrier. The r…
Spin-Torque Ferromagnetic Resonance Measurements of Damping in Nanomagnets
G. D. Fuchs, J. C. Sankey, V. S. Pribiag +8
We measure the magnetic damping parameter a in thin film CoFeB and permalloy (Py) nanomagnets at room temperature using ferromagnetic resonance driven by microwave frequency spin-t…
Dynamics of Spontaneous Magnetization Reversal in Exchange Biased Heterostructures
Zhi-Pan Li, Casey W. Miller, Igor V. Roshchin +1
The dependence of thermally induced spontaneous magnetization reversal on time-dependent cooling protocols was studied. Slower cooling and longer waiting close to the Nèel temperat…
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…
