- 論文の詳細を見る
Proton NMR of a layer structure antiferromagnet Cl(HCOO).'2C0(ND.)2'2D.0is investigated in detail near the transition temperature T.. The temperaturedependence of spontaneous staggered magnetizatic>n L. is found to be expressed by asingle exponential law with an index p=0.22%O.O2 in the measured temperaturerange 4?10 '<e<4?1O '. The very weak Ising-type anisotropy is predicted to beessential to the novel critical index. The origin for such a phase transition is discuss-ed, taking the possible canting interaction into account.
