Abstract
The Dy-Sc nitride clusterfullerene DyScN@C-I exhibits slow relaxation of magnetization up to 76 K. Above 60 K, thermally-activated relaxation proceeds via the fifth-excited Kramers doublet with the energy of 1735 ± 21 K, which is the highest barrier ever reported for dinuclear lanthanide single molecule magnets.
摘要
镝-钪氮化物团簇富勒烯DyScN@C-I在高达76 K的温度下表现出缓慢的磁化弛豫。在60 K以上，热激活弛豫通过能量为1735±21 K的第五激发态克莱默斯双重态进行，这是双核镧系单分子磁体中报道过的最高势垒。
