Abstract: Devices based on epitaxial garnet layers that exhibit a high magnetic anisotropy are disclosed. These garnet layers are produced by introducing a Co.sup.2+ or a species with 1, 2, 4, or 5 electrons in a 4d or a 5d electron orbital in the octahedral site of the garnet in conjunction with a typical anisotropy producing combination on the dodecahedral site. The contribution to magnetic anisotropy due to the typical combination on the dodecahedral site and the appropriate ion in an octahedral site is complementary.
