Current-Induced Dynamics in Almost Symmetric Magnetic Nanopillars
Weng Lee Lim, Andrew Higgins, Sergei Urazhdin
Magnetic nanodevices usually include a free layer whose configuration can be changed by spin-polarized current via the spin transfer effect, and a fixed reference layer. Here, we d…

Dynamical Regimes Induced by Spin Transfer in Magnetic Nanopillars
Weng Lee Lim, Andrew Higgins, Sergei Urazhdin
We demonstrate the predicted out-of-plane precession induced by spin transfer in magnetic nanostructures with in-plane magnetic field. We show that other magnetic excitations have…

Relationship between granularity of antiferromagnet and exchange bias
Sergei Urazhdin, Phillip Tabor, Weng-Lee Lim
We studied exchange bias in magnetic multilayers incorporating antiferromagent CoO doped with up to 35 atomic percent of Pt. The exchange bias increased with doping in epitaxial fi…
