Deconvoluting Reversal Modes in Exchange Biased Nanodots
Randy K. Dumas, Chang-Peng Li, Igor V. Roshchin +2
Ensemble-averaged exchange bias in arrays of Fe/FeF2 nanodots has been deconvoluted into local, microscopic, bias separately experienced by nanodots going through different reversa…
Magnetic Fingerprints of sub-100 nm Fe Nanodots
Randy K. Dumas, Chang-Peng Li, Igor V. Roshchin +2
Sub-100 nm nanomagnets not only are technologically important, but also exhibit complex magnetization reversal behaviors as their dimensions are comparable to typical magnetic doma…
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…
Anomalous Spontaneous Reversal in Magnetic Heterostructures
Zhi-Pan Li, Johannes Eisenmenger, Casey W. Miller +1
We observe a thermally induced spontaneous magnetization reversal of epitaxial ferromagnet/antiferromagnet heterostructures under a constant applied magnetic field. Unlike any othe…
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…
Bi-domain state in the exchange bias system FeF2/Ni
O. Petracic, Zhi-Pan Li, Igor V. Roshchin +4
Independently exchange biased subsystems can coexist in FeF2/Ni bilayers after various field-cooling protocols. We find double hysteresis loops for intermediate cooling fields, whi…
