2012/2/27
Motivated by recent experiments of successfully carving out stable carbon atomic chains from graphene [Meyer et al. Nature (London) 454, 319 (2008); Jin et al. Phys. Rev. Lett. 102, 205501 (2009)] we ...
Phase locking dynamics of dipolarly coupled vortex-based spin transfer oscillators
Phase locking dynamics dipolarly coupled vortex-based spin transfer oscillators
2012/2/27
Phase locking dynamics of dipolarly coupled vortices excited by spin-polarized current in two identical nanopillars is studied as a function of the interpillar distance L. Numerical study and analytic...
Spin current and polarization reversal through a single-molecule magnet with ferromagnetic electrodes
Spin current polarization reversal single-molecule magnet ferromagnetic electrodes
2012/2/27
We theoretically study the spin-polarized transport through a single-molecule magnet, which is weakly coupled to ferromagnetic leads, by means of the rate-equation approach. We consider both the ferro...
Impurity-assisted Andreev reflection at a spin-active half-metal-superconductor interface
Impurity-assisted Andreev reflection spin-active half-metal-superconductor interface
