Frustration Driven Stripe Domain Formation in Co/Pt Multilayer Films
J. E. Davies, O. Hellwig, E. E. Fullerton +3
We report microscopic mechanisms for an unusual magnetization reversal behavior in Co/Pt multilayers where some of the first-order reversal curves protrude outside of the major loo…
Direct Observation of Magnetic Gradient in Co/Pd Pressure-Graded Media
B. J. Kirby, S. M. Watson, J. E. Davies +4
Magnetometry and neutron scattering have been used to study the magnetic properties of pressure graded Co/Pd multilayers. The grading of the multilayer structure was done by varyin…
Disorder-induced magnetic memory: Experiments and theories
M. S. Pierce, C. R. Buechler, L. B. Sorensen +13
Beautiful theories of magnetic hysteresis based on random microscopic disorder have been developed over the past ten years. Our goal was to directly compare these theories with pre…
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…
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…
Disorder-induced microscopic magnetic memory
M. S. Pierce, C. R. Buechler, L. B. Sorensen +13
Using coherent x-ray speckle metrology, we have measured the influence of disorder on major loop return point memory (RPM) and complementary point memory (CPM) for a series of perp…
