Title: Experimental observation of magnetically dead layers in Ni/Pt multilayer films

Abstract

We report experimental evidence of the magnetically dead layers of Ni in sputter-grown Ni/Pt multilayers, studied with room-temperature magnetic circular dichroism and temperature-dependent superconducting quantum interference device magnetometry. The behavior of Curie temperature T{sub c} vs Ni sublayer thickness x results in T{sub c}=0 at x=4.0 {angstrom}, indicating the existence of magnetically dead Ni layers. For a sample x=2.2 {angstrom}, no magnetic moment is observed within experimental error over the whole temperature range of 2 to 300 K.
