ABSTRACT:
A device and method for controllably locally altering the magnetization direction in a body of magnetic material, whereby a layer of at least one of non-metallic material and a semi-metallic material is disposed on a surface of the body, on which layer is provided a body of magnetic material having a fixed magnetization direction, whereby both bodies of magnetic material are magnetically coupled across the interposed layer, the nature of this magnetic coupling being locally alterable by means of locally subjecting the layer to a controllable electric field.
