内容記述 | Charge-transfer effect under odd-parity crystalline electric field (CEF) is analyzed theoretically. In the quantum-critical metal β-YbAlB4, seven-fold configuration of B atoms surrounding the Yb atom breaks local inversion symmetry at the Yb site, giving rise to the odd-parity CEF. Analysis of the CEF on the basis of the hybridization picture shows that admixture of 4f and 5d wave functions at Yb with pure imaginary coefficient occurs, which makes magnetic-toroidal (MT) and electric-dipole (ED) degrees of freedom active. By constructing the minimal model for the periodic crystal β-YbAlB4, we show that the MT as well as ED fluctuation is divergently enhanced at the quantum critical point of the valence transition simultaneously with critical valence fluctuations. | |||||||||||
