Abstract
A ferromagnetic thin-film based magnetic field sensor having an electrically insulative intermediate layer with two major surfaces on opposite sides thereof with an initial film of an anisotropic ferromagnetic material on one of those intermediate layer major surfaces and a superparamagnetic thin-film on the remaining one of said intermediate layer major surfaces.
