本文通过静水压力和单轴压力下的磁化和比热测量，研究了几何挫折对T-N = 4.2 K下钇基三角形晶格化合物YbCuGe反铁磁有序的影响。当静水压力P达到1.34 GPa时，T-N几乎没有变化。相反，T-N随着P沿六角形a轴的施加而增加，而T-N随着P沿c轴的施加而减少。仅P b| |a的T-N增加表明该化合物中Yb离子三角形晶格固有的受挫释放。
We have studied the effect of geometrical frustration on the antiferromagnetic order in the Yb-based triangular lattice compound YbCuGe below T-N = 4.2 K by the measurements of magnetization and specific heat under hydrostatic and uniaxial pressures. By applying hydrostatic pressure P up to 1.34 GPa, T-N hardly changes. By contrast, T-N increases as P is applied along the hexagonal a axis, while T-N decreases by the application of P along the c axis. The increase of T-N only for P||a suggests the release of the frustration inherent in the triangular lattice of Yb ions of this compound.
