Abstract
Cu/Co/Cu/NiFe multilayers were prepared by molecular beam epitaxy and their magnetoresistive (MR) properties in dc and ac magnetic field were studied. With a view to application such as MR head, minor loops of MR transfer curves with applied fields of ±50 Oe were particularly investigated. By optimizing the thickness of each layer, a linear and nonhysteretic MR response was obtained. The output voltage was roughly estimated as two and a half times that of a conventional NiFe element in an ac magnetic field at 50 Hz.Keywords
