Abstract

It is proposed to epitaxially grow hexaferrite films on garnet single crystal substrates. As an example, hexaferrite BaFe(12)O(19), which supports magnetic bubble domains with stability Q is approx. equal to 3.6 and bubble diameter is approx. equal to 0.3 microns, can be grown on Nd(3)Ga(5)O(12). A <111> orientation is suitable.

A <111> orientation is suitable.

Other orientations and hexaferrite film - garnet substrate combinations are possible.
