施加压力抑制价态波动化合物ybincu4的价态转变温度，稳定高温（HT）磁相。研究了Cu-NQR在1.68GPa压力下对ybincu4电子态的微观影响。压力的影响表现在四极频率的增加上，主要是由细胞体积的缩小引起的。而HT相的自旋晶格弛豫时间t1和LT相的恒定金属态T1T与温度无关的行为几乎不受压力的影响，这表明在1.68GPa以下，HT相和LT相的电子态对压力不敏感。
Application of pressure on the valence fluctuating compound YbInCu4suppresses the valence transition temperature and stabilizes the high-temperature (HT) magnetic phase. We have investigated microscopically the pressure effect on the electronic states of YbInCu4with Cu–NQR under up to 1.68GPa. The effect of pressure appears in the increase of quadrupole frequencies mainly caused by shrinking of the cell volume. Whereas the temperature-independent behavior of spin-lattice relaxation time T1in the HT phase and T1T=constant metallic behaviour in the LT phase are hardly affected by pressure, indicating that the electronic states in both HT and LT phases are rather insensitive to pressure up to 1.68GPa.
