MAGNETOOPTIC MATERIAL Russian patent published in 2014 - IPC C30B29/28 C30B19/12 H01F10/24 H01F10/28 G02F1/09

Abstract RU 2522594 C1

FIELD: physics.

SUBSTANCE: magnetooptic material is an epitaxial monocrystalline film of iron garnet of the composition (YBi)₃(FeGa)₅O₁₂, which is grown on a substrate of nonmagnetic garnet with a high lattice constant $a = 12,380 \overset{_{o}^{/}}{A} - 12,560 \overset{_{o}^{/}}{A} .$ The epitaxial film contains 0.1-0.4 formula units of Mg²⁺ ions. The substrate of nonmagnetic garnet can be made from (GdCa)₃(GaMgZr)₅O₁₂, or Ca₃(NbLi)₂Ga₃O₁₂, or Ca₃(NbMg)₂Ga₃O₁₂, or Ca₃(NbZr)₂Ga₃O₁₂. The disclosed material has a magnetooptic figure of merit of 56-60 deg/dB at λ=0.8 mcm, 350-380 deg/dB at λ=1.3 mcm, coercitive force of about 2.5-15.3 Oe.

EFFECT: obtaining high-contrast images by thermomagnetic recording.
