摘要：

The critical and irreversibility phase boundaries of the d = 3 dilute uniaxial antiferromagnet Fe0.60Zn0.40F2 have been determined under strong magnetic fields by magnetization measurements. Our data reveal that the random-held-induced glassy phase, previously observed in the upper part of the (H, T) phase diagram for highly diluted samples (Fe concentration x congruent to 0.3), is extensive to higher values of x.
