Abstract

In accordance with various embodiments, at least one magnetic shield for a magnetoresistive (MR) element has one or more lateral hard magnets and a coupling layer contactingly adjacent both the MR element and the hard magnet. The coupling layer concurrently magnetically decouples the MR element while magnetically coupling the hard magnet.
