A magnetic multilayer film having magnetoresistance (MR) is prepared by depositing at least two magnetic thin films having different coercive forces while interposing a non-magnetic thin film therebetween. A first magnetic thin film having a lower coercive force has a squareness ratio SQ.sub.1 of 0.01-0.5,...http://www.google.es/patents/US5514452?utm_source=gb-gplus-sharePatente US5514452 - Magnetic multilayer film and magnetoresistance element
