Temperature-dependent magnetization reversal in (Co/Pt)/Ru multilayers (2008)
Davies, Joseph E., Hellwig, Olav, Fullerton, Eric E., Liu, Kai
Antiferromagnetically coupled (Co/Pt)/Ru multilayers with perpendicular anisotropy have been shown to exhibit both vertically and laterally correlated magnetization reversal modes. In this work, the...
A Magnetic and Moessbauer Spectral Study of Core/Shell Structured Fe/Au Nanoparticles (2005)
Cho, Sung-Jin, Shahin, Ahmed M., Long, Gary J., Davies, Joseph E., Liu, Kai, Grandjean, Fernande, ...
Fe/Au nanoparticles have been chemically synthesized through a reverse micelle reaction and investigated by both conventional and synchrotron based x-ray diffraction and by magnetic and Moessbauer...
Magnetization Reversal and Nanoscopic Magnetic Phase Separation in Doped La1-xSrxCoO3 (2005)
Davies, Joseph E., Wu, J., Leighton, C., Liu, Kai
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 curve (FORC) method to...
Davies, Joseph E., Hellwig, Olav, Fullerton, Eric E., Jiang, J. S., Bader, S. D., Zimanyi, G. T., ...
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, the reversal...
Hysteresis loops of Co-Pt perpendicular magnetic multilayers (2003)
Mobley, David L., Pike, Christopher R., Davies, Joseph E., Cox, Daniel L., Singh, Rajiv R. P.
We develop a phenomenological model to study magnetic hysteresis in two samples designed as possible perpendicular recording media. A stochastic cellular automata model captures cooperative behavior...
