摘要：
We report measurements of the low temperature magnetic properties of a-(Gd1-xTbx)2Cu random anisotropy alloys. Relaxations of the remanence were found to follow closely a ln(t) (or t(-alpha)) relation. The remanence and coercivity have an exponential temperature dependence for x > 0.3 and follow a power law relation for x < 0.3. This behaviour suggests a cross-over in the nature of the low temperature thermally activated processes.
