Switching characteristics of submicron dimension Permalloy sandwich films

Submicron magnetoresistive sandwich cells of various sizes are fabricated and their magnetic properties are studied. A novel coupling mechanism of magnetostatic origin has been found to be mainly responsible for unique switching characteristics in cells with small length to width ratio.
