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…
Angular Dependence of Vortex Annihilation Fields in Asymmetric Co Dots
Randy K. Dumas, Thomas Gredig, Chang-Peng Li +2
Shape asymmetries in nominally circular nanomagnets provide a potential means for vortex chirality control. However, in realistic arrays their effects are challenging to probe sinc…
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…
