Analytical model in a weakly coupled sandwich for memory purposes

A simple analytical model explains giant magnetoresistive properties in a weakly coupled sandwich with two magnetic components. The model describes in detail a new storage mechanism in which the minor loop's slope depends on its past magnetic histories. A new type of solid-state giant magnetoresistance memory based upon this mechanism has been realized by experiments. Furthermore, some important factors included in nondestructive readout capability are also analyzed by this model. (C) 1996 American Institute of Physics.
