Abstract :
In the framework of DOM (Discrete Orientation Model) the movement of a magnetic moment looks like a Markov chain with a finite number of states coinciding with points (edges) of lattice. It is possible to get asymmetrical spectrum within a discrete approximation corresponding to non-potential drift field by introducing a non-symmetric stochastic matrix as a generator of dynamics. This leads to precession of magnetic moment not around but between directions of easy magnetization.
