High-frequency propagation and failure of asymmetric half-disk field access magnetic bubble device elements

Abstract

Abstract-High-frequency propagation characteristics and failure modes in 1 4 -p~ period, 1.8-pm gap, asymmetric half-disk field-access device were studied using a high-speed optical sampling technique. Propagation elements as well as normal and hand gun corners and chevron structures were included. The operating bias margin at 1 MHz, for a structure that had 1.
