Abstract
On the basis of band calculation, the p - f mixing parameters and the spin-orbit splittings in La-monopnictides are evaluated, and temperature and pressure dependence of carrier number in Ce-monopnictides are studied. It is shown that in La-monopnictides the strongly correlated electron-hole pair effect is important, while in Ce-monopnictides the occupied bonding 4 f level near the Fermi level plays the most important role in the pressure effect. However, the electron-hole weak pair effect is dominant for the temperature dependence. Various anomalous properties are explained through the above model.Keywords
