摘要
WITH the temperature decreasing, Cr<sub>100-x</sub>Fe<sub>x</sub>（18≤x≤25） alloys exhibit first a transition from a paramagnetic （PM） state to a ferromagnetic （FM） state and then a second transition from the FM state to a re-entrant spin glass state. There are mainly two pictures interpreting the re-entrant spin glass behavior. One as-
