Ab Initio theory of the Gilbert damping in random ferromagnetic alloys
Original language description
We present an ab initio theory of the Gilbert damping in ferromagnetic alloys with substitutional disorder. The theory is based on nonlocal torques represented by nonrandom, site-off-dagonal, and spin-independent matrices. The formalism is developed for the relativistic tight-binding linear muffin-tin orbital (TB-LMTO) method and the coherent potential approximation (CPA). The CPA vertex corrections play a crucial role for the internal consistency of the theory and for its exact equivalence to other first-principles approaches based on random local torques. The theory is illustrated by calculations for various random transition metal alloys. Results are in a reasonable agreement with other calculations and accessible experimental data.
