中文摘要	Unusual magnetization process has been observed in Gd5Ge4 prepared with commercial Gd of 99.9 wt %. First, the zero-field-cooled M(H) curves below 25 K contain a significant low-field ferromagnetic (FM) component followed by an unusually broadened field-induced antiferromagnetic (AFM)-FM transition, which was not observed in previous reports no matter if the sample owns a residual FM component or not. Second, the M(H) curves at 4.2 K collected using pulsed magnetic fields reveal some unusual dynamics on the low-field FM state and the following AFM-FM transition. Thus, the present sample of Gd5Ge4 is a new example showing complexity of the influence from impurities of Gd upon the magnetization process. (c) 2011 American Institute of Physics.
