L. Zhou et al., THEORETICAL-STUDIES OF THE MAGNETIC MULTIVALUED RECORDING IN COUPLED MULTILAYERS, Physical review. B, Condensed matter, 55(6), 1997, pp. 3693-3698
In this paper, we discuss the possibilities of realizing the magnetic
multivalued (MMV) recording in a magnetic coupled multilayer. The hyst
eresis loop of a double-layer system is studied analytically, and the
conditions for achieving the MMV recording are given. The conditions a
re studied from different respects, and the phase diagrams for the ani
sotropic parameters are given in the end.
