Abstract

The switching mechanism in ring-shaped pseudospin valves was discussed. The magnetization reversal was studied as functions of the ratio of the inner to the outer diameter of the ring, and of the outer diameter when that ratio was constant on a pseudospin valve system. Switching fields were obtained from the simulation.
