Magnetization reversal in YIG/GGG(111) nanoheterostructures grown by laser molecular beam epitaxy.

Thin (4-20 nm) yttrium iron garnet (YFeO, YIG) layers have been grown on gadolinium gallium garnet (GdGaO, GGG) 111-oriented substrates by laser molecular beam epitaxy in 700-1000 °C growth temperature range. The layers were found to have atomically flat step-and-terrace surface morphology with step height of 1.8 Å characteristic for YIG(111) surface.
