| 摘 要： | 采用固相烧结法制备尖晶石结构Li1.33Mn1.67O4样品. 不同磁场下的直流磁化率曲线、 磁滞回线和交流磁化率均表明该样品在低温呈团簇自旋玻璃态. 通过计算材料的几何失措因子, 可知掺杂非磁性Li离子破坏了失措的Kagome点阵, 从而诱导铁磁与反铁磁相互作用的竞争, 使体系呈自旋玻璃态.

| Abstract: | The sample of Li1.33Mn1.67O4 with spinel structure was prepared by means of solid state sintering technology. The ground state of Li1.33Mn1.67O4 shows cluster spin glass state identified by analyzing DC magnetization under different magnetic fields, magnetic hysteresis and AC susceptibility. The calculating results of geometrical frustration show that nonmagnetic Li+\|doping destroyed the frustrated kagome lattice, induced the competition between ferromagnetic and antiferromagnetic interaction, and made the system present spin glass state. |
