The manifestation of one-dimensional noncollinear spin-dependent scattering on magnetized nano-element structures

The scattering of spin-polarized electron and neutron waves on a magnetized magnetic potential (rectangular) barrier is studied in magnetic (nano- element) nanostructures. The existence of two pre- ferred directions for the polarization of the incident wave and the magnetic field of the magnetized barrier provide a new degree of freedom—the angle between them or degree of noncollinearity, which determines the spin-dependent transport properties. We analyze exact expressions of spin injection and spin-polarization transport obtained for dependencies of transmission and reflection coefficients, degrees of polarization, orienta- tion of the polarization vectors, and energy of the scattered waves in the sub-barrier and above-barrier energy regions. It is shown that the variation of the noncollinear angle can lead to the complete destruc- tion of the polarization of the scattered waves, and substantial reorientation of the polarization vectors.
