Abstract

We have grown thin films and multilayers of several ferrite materials with the spinel structure by pulsed laser deposition of stoichiometric targets. Epitaxial films can be grown on a variety of substrates including MgO, Al2O3, MgAl2O4, Y-stabilized ZrO2 (YSZ) and SrTiO3. Films on Mg- and Al-containing substrates have a low saturation Magnetization, Ms, while films on YSZ and SrTiO3 exhibit bulk values of Ms. The anisotropy can be lowered by a post growth anneal, resulting in a film with a permeability of 28.
