抄録

Proton NMR of two-dimensional Heisenberg like antiferromagnets Cu(HCOO)2·2CO(ND2)2·2D2O (CuFUD) and the isostructural Cu(HCOO)2·4D2O (CUF4D) are examined in detail near and below the transition temperature TN. By eliminating the effect of field inducd magnetization due to the canting mechanism, the very growing feature of spontaneous staggered magnetization L0 below TN is observed. For CuFUD, a single exponential law with β=0.22 is obtained in the whole measured temperature range. For CuF4D, however, a crossover phenomenon is observed. β=0.22 for ε(=1−T⁄TN)>ε*(=5×10−2) and β=0.30 for ε<ε*. Comparing the results for CuFUD and for CuF4D, a possible origin for such a novel critical index is discussed.
