Magnetic domains in a TbGdFeCo film

MDT-file: Download

Magnetic domain landscape in a TbGdFeCo film. The 180 nm thick film was deposited on a 100 nm thick Cr underlayer/glass at 200 C and 4 mTorr argon gas pressure using DC magnetron sputtering. Similar multi-layer films have been used for the Bose-Einstein condensation of rubidium atoms on an atom chip.
