Abstract
A method and device for detecting Neel wall segments in a cross-tie memory system involves applying a magnetic field to the Neel wall segments of a given polarity so that these Neel wall segments expand into a transverse domain. The transverse domain is then sensed with a magnetoresistive detector.
