Yb4As3 shows anomalous transport phenomena below the phase-transition temperature associated with an order-disorder transition due to the atomic arrangement between Yb3+ and Yb2+. Although the LIII spectrum shows no change in valence above and below the temperature, the large increase of the trivalent component has been clearly observed with increasing pressure. Comparing the pressure- and temperature-dependent resistivity between Yb4As3 and Yb4Sb3, it is suggested that the anomalous transport properties of Yb4As3 are due to a characteristic electronic structure modulated with the phase transition.
