Abstract

The electrical resistivity ρ and the Hall resistivity ρ H of LaAg 1- x In x (0< x <0.7) have been measured and analyzed on the basis of two-band model. The calculated temperature dependence of ρ and ρ H agree well with the experimental ones. The s electrons are about 0.2 per unit cell for all x and change little at the band Jahn-Teller transformation temperature T M . The d -hole is in a range of 0.6–0.9 per unit cell and its number changes at T M . The total s -electron conductivity is about 30% of all and is very large compared with YZn and heavy rare earth RAg 1- x In x (R=Gd, Tb and Dy).
