摘要：
The magnetic properties of MgZn2-type Zr(Cr1-xFex)(2) (0.3 less than or equal to x less than or equal to 0.7) and Zr(Cr1-xFex)(2)H-y (y similar to 3) alloys have been investigated. Arrott plots showed no evidence for ferromagnetic ordering. ZFC/FC magnetization and Mossbauer spectroscopic data indicated spin glass-like freezing. Saturation moments in the unhydrided alloys decreased with decreasing Fe concentration, vanishing for x approximate to 0.3. Hydrogen absorption made magnetic moments increase and freezing temperatures decrease. (C) 1999 Elsevier Science B.V. All rights reserved.
