Transmission spectrum through the single magnetic/electric barrier and spin rotation of transmitted/reflected electrons. (a) The contour plot of the transmission probability as a function of the incident angle and the incident energy, for a fixed barrier width d = 1 and height V = 4, for magnetic field B = 0. (b) The spin orientation of the incident (black arrows), transmitted (red arrows), and reflected (green arrows) electrons as a function of the incident angle and energy. The lengths of the arrows indicate the transmitted or reflected probabilities. The magnetic field unit is B0 = 1 T, the energy unit is E0 = 16 meV, and the length unit is lB = 26 nm.
