摘要: It has been shown that the Fe3+ ions in distorted perovskite GdFeO3 become ordered antiferromagnetically at 650 K and ordering arrangement is GxFz Bertaut's (1963) notation. The canted moment measured temperatures below 77 K, found to produce an effective field of 310 Oe gadolinium sites opposing moment. induced susceptibility Gd3+ zero applied direct opposition resultant Fe along c axis. specific heat temperature range 0.5 K
