　　With Monte Carlo simulations and molecular dynamics simulations, we investigate the magnetic domain-wall dynamics in low dimensions and at a zero or low temperature.Based on the lattice models with quenched disorder and under different driving fields, we systematically study the pinning-depinning transition and relaxation-to-creep transition of domain-wall motion.Results are compared with experiments and other theories.
