Crystallographic transformation and electronic properties in the CsCl-type compounds PrAg1-xInx

Abstract

The electrical resistivity and Hall resistivity of PrAg1-xInx have been measured. The crystal structure at room temperature is of CsCl type for x or=0.7 it decreases with increasing temperature. The value of Delta rho / Delta T at room temperature has a minimum at x=0.6. The ordinary Hall coefficient R0 is positive at x=0, its magnitude increases with x until x=0.3, where it decreases suddenly as the transformation begins. The relationship between the transformation and the electronic properties is discussed.
