摘要

对LuB12中175Lu的核磁共振线宽和自旋晶格弛豫率的分析假设在T*~150 K时结构跃迁到由协同扬-泰勒效应引起的晶格畸变的长程铁畸变阶态。报道的实验事实表明，这种转变是其他稀土十二硼化物的特征。

Structural Transition in Dodecaborides According to NMR in LuB12

Analysis of the nuclear magnetic resonance linewidth and spin-lattice relaxation rate of ¹⁷⁵Lu in LuB₁₂ assumes a structural transition at T*~150 K into a state with a long-range ferrodistortive order of lattice distortions caused by the cooperative Jahn–Teller effect. The reported experimental facts imply this transition to be characteristic of other rare-earth dodecaborides.
