Abstract

The pressure dependence of the electric field gradient (EFG) in the AgIn2 intermetallic compound was measured from zero up to 35 kbar using the time differential perturbed angular correlation technique in111Cd. The unit cell volume and thec/a ratio variations with pressure were measured up to 80 kbar. The temperature dependence of the cell parameters was also measured, in a range varying from 300 K up to 458 K. The relationship of these results showed that the contribution of the lattice thermal expansion to the EFG variations is about 1/3, a small but not negligible part. The estimated EFG volumetric dependence is at variance with the systematic results found in pure metals.
