摘要：

A spin-polarized electrical current leads to a variety of periodical magnetic structures in nano-stripes. In the presence of the Orsted field, which always assists an electrical current, the basic types of magnetic structures, i.e., a vortex-antivortex crystal and cross-tie domain walls, survive. The Orsted field prevents saturation of the nanostripe and a longitudinal domain wall appears instead. Possible magnetization structures in stripes with different geometrical and material properties are studied numerically and analytically. (C) 2015 AIP Publishing LLC.
