摘要：

dc magnetization measurements on the quasi-one-dimensional halogen-bridged platinum complex [Pt(en)2][Pt(en)2I2](ClO4)4 (where en is ethylenediamine) reveal a magnetic-field-induced strong diamagnetic transition at fields above 20 kOe. The diamagnetic signals are as large as 3.5% - 72% of complete diamagnetism and show large fluctuations. A sharp diamagnetic-paramagnetic transition occurred around 180 K. There is no anisotropy visible in the diamagnetic behavior, in contrast to the one-dimensional electronic and crystal structure of this material.
