Positron annihilation studies of SmS and (Smsub(0.8)Gdsub(0.2))S across valence transitions
- 1. Reactor Research Centre, Kalpakkam (India)
Description
Positron life-time measurements have been made in SmS under pressure up to 15 kbar and in (Smsub(0.8)Gdsub(0.2))S at temperatures from 10 K to 300 K. A discontinuous change in life-time was observed at the valence transition. This is explained on the basis of the changes in the lattice parameter and the electronic structure of these compounds.
