Abstract
In the present paper, the magnetic susceptibility have been studied under the effect of pressure at constant temperature in samarium chalcogenides (SmX, X=S, Se and Te). The samarium chalcogenides have predicted the pressure induced structural and electronic transition from NaCl structure (FCC lattice) to CsCl structure (BCC lattice). The f energy level of electrons in the compounds (SmX, X=S, Se and Te) have been shifted towards 5 d conduction band due to the influence of pressure at constant temperature. The variation of the magnetic susceptibility under the effect of pressure at constant temperature have been calculated. The calculated values and parameters are in close agreement with the experimental results.
Highlights
The chalcogenide material containing the chalcogen element S, Se and Te have wide application in technological uses like thermo-electrics, non-linear optical materials and photoelectric
