Abstract :
Micromagnetic calculations were performed on ring-shaped pseudospin valves with different outer diameters of the ring while keeping the aspect ratio between the inner and outer diameters constant, and with constant outer diameter while the aspect ratio of the inner to outer diameter was varied. Switching fields of this system were obtained from the simulation and will be discussed.
