THIN-FILM STRUCTURE OF A MAGNETIC FIELD SENSOR WITH A MAGNETORESISTIVE MULTILAYER SYSTEM HAVING ELECTRON SCATTERING SPIN DEPENDENCY

摘要

A thin-film structure of a magnetic field sensor includes a multilayer system having enhanced magnetoresistive effect and exhibiting spin dependency of electron scattering at an interface as well as diffuse scattering of unreflected electrons. The interface which reflects spin-dependently is intended to lie between respective neighboring layers of magnetic and nonmagnetic material. The materials have lattice dimensions matched to one another and are immiscible. The layers of magnetic material are preferably divided into spin-selectively reflecting and scattering regions.
