Abstract

A four gun magnetron sputter deposition chamber equipped with in-situ spectroscopic ellipsometry is described, and the results of precisely controlled multilayered metallic and dielectric materials are reported. These structures have applications in magneto-optic memories, as well as giant magneto resistance and spin-valve magnetic read-heads.
