MAGNETIC AND STRUCTURAL-PROPERTIES OF LASER-DEPOSITED LITHIUM FERRITEFILMS

Thin films of lithium-zinc ferrite have been grown by pulsed laser dep osition techniques under varying oxygen partial pressures. X-ray diffr action measurements showed the films grew epitaxially onto the (001) M gO substrates. Films grown at lower oxygen pressures displayed cubic a nisotropy with parameters close to bulk values, with the film grown at the lowest pressure having the highest saturation magnetization and t he narrowest ferromagnetic resonance linewidth. The film grown at the highest pressure displayed in-plane uniaxial anisotropy and a relative ly low magnetization.
