Spin glass dynamics in RKKY interacting disordered magnetic system

doi:10.1088/1674-1056/19/9/097105

Abstract Using the dynamical Monte Carlo method we investigate the nonequilibrium effects in RKKY-coupling disordered spin glass. By the simulation we reproduce the well-known aging and memory phenomena and find the energy relaxation at a certain temperature happens only to the corresponding spins, which directly causes the nonequilibrium effects. Combining the master equation and the energy relaxation we analyse these phenomena and explain them from the dynamical perspective.

Keywords: RKKY spin glass aging memory
