| Popis: |
A lambda anomaly was observed in the nuclear heat capacity of a single crystal of praseodymium known not to order down to 1.8 K. The anomaly is associated with a cooperative magnetic ordering of the hexagonal-site nuclei at 25--30 mK of the type discussed by Murao. This result is in contrast to earlier calorimetric measurements where ionic order has precluded cooperative nuclear processes. The cooperative anomaly is suppressed by a field of 1.5 T. (AIP) |
