FEASIBILITY OF LOW POWER ANNEALED MAGNETIC FILMS.

Abstract

The feasibility of using annealed low power thin permalloy films for information storage in computer memories was demonstrated. A memory exerciser was designed and built for simulation of memory operation. The optimum post-deposition anneal of 10 minutes at 300 C in a magnetic field along the transverse axis produced a reduction of 1/3 to 1/2 in read-drive current to as low as 200 ma without increasing the dispersion enough to make the films unusable. The switching time of annealed films was several nanoseconds, approximately the same as that for unannealed films. The annealing process was also shown to be useful for a 'bicore' type nondestructive readout film device. (Author)
