Abstract :
Random switching of magnetization is studied using a continuous master equation derived for magnetization dynamics driven by a jump-noise process. This paper is concerned with numerical analysis of the Kramers-Brown approximation as well as with low temperature random magnetization switching where the so-called phenomena of macroscopic quantum tunneling of magnetization has been experimentally observed and theoretically predicted.
