Abstract

A conductorless chip employing C-bar type elements switches bubbles by reversing the drive field momentarily. The operation of switches by drive field reversing is based on the non-reciprocal design of the permalloy pattern. Instead of propagating backward when the drive field is reversed, the bubbles follow a new path of permalloy patterns.
