Magnetic properties of the azafullerene Gd2@C79N are studied by SQUID magnetometry. The effective exchange coupling constant jGd,e between the Gd spins and the spin of unpaired electron residing on the single-electron Gd–Gd bond is determined to be 170 ± 10 cm−1. Low temperature AC measurements revealed field-induced millisecond-long relaxation of magnetization.

单电子 Gd-Gd 键 Gd2@C79N 中的巨交换耦合和场诱导的磁化慢弛豫
通过 SQUID 磁力计研究了氮杂富勒烯 Gd 2 @C 79 N 的磁性。Gd自旋与位于单电子Gd-Gd键上的不成对电子的自旋之间的有效交换耦合常数j Gd,e确定为170±10 cm -1。低温交流测量揭示了磁场诱导的毫秒长的磁化弛豫。
