First principles calculations of magnetoresistance as a function of external field in layered Co-Re hexagonal-close-packed superlattices

The calculations of magnetoresistance for a layered Co/Re hcp(101̄0) superlattice as a function of external magnetic field were performed. It was found that the phenomenological model qualitatively described the density function calculations. The results of first-principles computations of the quantum relativistic resistivity tensor as a function of external magnetic field, were also discussed for a layered Co-Re heterostructures. The results show that the spin-flop (SF) transition greatly effects the anisotropic magnetoresistance (AMR), but slightly effects the giant magnetoresistance (GMR).
