Paek, WB Kim, J Lim, SH 2024-01-21T07:04:24Z 2024-01-21T07:04:24Z 2021-09-02 2004-06 0370-1972 https://pubs.kist.re.kr/handle/201004/137560 Ferromagnetic ordering at room temperature is observed in amorphous Ge100-xCrx (x in at.%) thin films fabricated by thermal co-evaporation over a wide composition range up to x = 39. High resolution transmission electron microscopy results indicate that the microstructure is mostly amorphous, except for at x = 15 (close to eutectic composition) and 39 where crystalline precipitates of Ge and the intermetallic Ge19Cr11 compound are respectively formed in an amorphous matrix. The saturation magnetization at room temperature exhibits a maximum value of 2.5 emu/cc at x = 29 and the compositional dependence of saturation magnetization is supported by the microstructural results.
