Suppressed magnetization in LaCaMnO/YBaCuO superlattices
A. Hoffmann, S. G. E. te Velthuis, Z. Sefroui +4
We studied the magnetic properties of LaCaMnO / YBaCuO superlattices. Magnetometry showed that with increasing YBaCuO layer thic…
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…
Magnetic Vortex Resonance in Patterned Ferromagnetic Dots
V. Novosad, F. Y. Fradin, P. E. Roy +3
We report a high-resolution experimental detection of the resonant behavior of magnetic vortices confined in small disk-shaped ferromagnetic dots. The samples are magnetically soft…
Positional Disorder, Spin-Orbit Coupling and Frustration in GaMnAs
Gregory A. Fiete, Gergely Zarand, Boldizsar Janko +2
We study the magnetic properties of metallic GaMnAs. We calculate the effective RKKY interaction between Mn spins using several realistic models for the valence band structure of G…
