Tunnel magnetoresistance in MgO-barrier magnetic tunnel junctions with bcc-CoFe(B) and fcc-CoFe free layers
We have investigated the spin tunneling transport in magnetic tunnel junctions (MTJs) with Co40Fe40B20, Co50Fe50, and Co90Fe10 free layers which were deposited on the lower electrode consisting of the...

Configurational anisotropy in hexagonal arrays of submicron Co elements
The angular dependence of the in-plane magnetization reversal in hexagonally ordered Co arrays has been investigated. A sixfold anisotropy has been observed which mirrors the structural symmetry of th...

We discuss the structure of the so-called "vortex" domain walls in soft magnetic nanoparticles. A wall of this kind is a composite object consisting of three elementary topological defects: two edge defects with winding numbers –1/2 and a vortex with a winding number +1 between them. We provide a qualitative model accounting for the energetics of such a domain wall. ©2006 American Institute of Physics
