摘要：

A new ordering vector k=(2/a)(0, 2/3, 2/3) for fcc antiferromagnets has been found by neutron-diffraction experiments at nanokelvin temperatures in the nuclear-spin system of a Cu65 single crystal. The corresponding reflection together with the previously observed (100) Bragg peak show the presence of three antiferromagnetic phases, separated by two first-order phase transitions, as the external magnetic field is varied between zero and Bc=0.25 mT. The kinetics of the transitions was observed to be on the order of seconds. © 1990 The American Physical. Society.
