摘要: Magnetization measurements have been performed on the Haldane gap materials (CH 3 ) 4 NNi(NO 2 (TMNIN) and Ni(C H 10 N (ClO (NINAZ) in pulsed high magnetic fields. TMNIN shows a typical magnetization profile of material with energy 4.1 K. Quenching appears around 2.7 Tesla(T) saturation is obtained above 30 T. In NINAZ, however, quenching at T reflecting large magnitude 44.3
