Effects of Intrinsic Spin-Relaxation in Molecular Magnets on Current-Induced Magnetic Switching

Current-induced magnetic switching of a single magnetic molecule attached to two ferromagnetic contacts is considered theoretically, with the main emphasis put on the role of intrinsic spin relaxation processes. It is shown that spin-polarized current can switch magnetic moment of the molecule, despite of the intrinsic spin relaxation in the molecule. The latter processes increase the threshold voltage (current) above which the switching takes place.
