YIG film evolution under variable external magnetic field

MDT-file: Download

Yttrium iron garnet (YIG) film on gadolinium gallium garnet (GGG). The domain structure is changed under influence of vertical magnetic field (+100 G, +60 G, +40 G, 0 G, -20 G).

The sample was kindly provided by Prof. F.V. Lisovskiy, Institute of Radioengineering and Electronics RAS.
