Low H(c) permalloy films can be fabricated by laminating several layers of NiFe separated by nonmagnetic layers. For example, 3000 Angstroms total NiFe films with H(c) = 0.5 to 1.0 Oe can be fabricated by evaporation of three NiFe layers of 1000 Angstroms thickness, separated by Cr, Au, SiO, etc. (two layers).
