Abstract
The change in the direction of the circumferential lattice magnetization by using the spin-polarized current is found by magnetic force microscopy to be possible for square epitaxial Fe (001) microstructures in the basic state. Such a change of the magnetization occurs when applying the magnetic saturation field to the structure with the subsequent switching off of the field accompanied by passing the current with the density above a certain threshold on the order 1012 A/m2 through the structure. In the basic state of the structure, the change of the magnetization depends not only on the current density but also on the spin polarization and the region of the current flow. The effect of the spin-polarized current on the circumferential magnetization of the structure, which is related to the injection of spins by the current, is discussed.
