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 preferred 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, orientation 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 destruction of the polarization of the scattered waves, and substantial reorientation of the polarization vectors.
