Abstract
A magnetic field responsive device which includes: an electrically insulating substrate (2), a layer of an electrically conductive soft magnetic material (3), a layer of giant magneto-resitive (GMR) material (5) arranged in electrical contact with ethe layer of electrically conductive soft magnetic material, the thickness of the GMR material layer being not greater than twice the mean free path of an electron in the said GMR material, the layers being arranged in any order or position on the substrate and having opposed directions of mangetisation in zero magnectic field.
