抄録

An all-permalloy single mask level design for a serial loop circuit has been developed and successfully operated using 3 mu m bubbles. The design of individual elements for a single level circuit such as generator, replicator and annihilator which were compatible with half-disk propagation patterns was investigated, and optimization of permalloy and SiO//2 spacer film thickness was achieved. The small capacity tests chips fabricated provided 13-16 oe ″window margins″ with circular drive field ranges of 40 to 50 oe at 100 kHz. The critical stretching pulse phase margin for replication, which was the minimum phase margin for all functions, was found to be 10 degrees. The design and characteristics are discussed including operating margin dependence on frequency and temperature.
