Description: This photograph shows a crystal tetragonal plate of TbFe2Ge2 grown by dissolving the starting elements in Sn flux at ˜1200°C, then slowly cooling down to 500-800°C. This material has a tetragonal structure and crystals grow as thin plates with very smooth surfaces. Iron is non-magnetic in the RFe2Ge2 series and most rare earths order antiferromagnetically, showing extreme magnetic anisotropy.
