Abstract: An enhanced output signal is provided by the coupling of a magnetic bubble to a magnetoresistance detector element when the familiar rotating in-plane drive field is set at an amplitude such that the presence of a bubble results in a change in frequency in signal exhibited by the detector element due to the in-plane field. The largest signals yet achieved resulted from an integrated expansion detector, guard rail arrangement with a meandering magnetoresistance element when operated in this manner.

Abstract: A relatively large output signal is achieved from an expanded magnetic domain by a relatively long magnetoresistance element in the path of the domain. The relatively long element is formed with a minimum loss of space by including within the magnetoresistance element portions of the already present magnetic elements which define the path along which the domain moves. Domain movement and expansion is due to the geometry of the path-defining elements and is responsive to a magnetic field rotating in the plane of domain movement.
