要旨

The following issues concerning UPd2Al3 are addressed: (i) its anisotropic magnetic phase diagram which can be explained by domain-reorientation effects, (ii) the coexistence between magnetically ordered local 5f moments and Cooper pairs formed by weakly delocalized 5f states and (iii) distinct anomalies in the sample length measured both vs T and B, suggesting a strongly undercooled first-order transition at B* (T) less than or similar to B-c2(T) for T < T* similar or equal to 0.8 T-c.
