摘要：

The critical behavior of Cr near the first-order antiferromagnetic transition at 38.5°C has been studied by neutron scattering. This study reveals the existence of a sharp central peak at the satellite position in a narrow temperature range just above TN. It exhibits a very singular temperature dependence such as the two-dimensional planar model predicts. Such unusual behavior supports the conjecture that the two-dimensional planar model is realized in the critical region of Cr. © 1979 The American Physical Society.
