Abstract: | The structural and elastic properties of cerium chalcogenides (CeZ, Z = S, Se, Te) under high pressure have been investigated
by using the potential model considered up to third nearest neighbor interaction. The computed values of B1-B2 phase transition
pressure, equation of state (compression curve), bulk modulus, its first order pressure derivative and elastic constants in
the case of cerium chalcogenides agree well with the experimental results. The present study shows the anomalous behavior
of cerium chalcogenides in comparison to the alkaline earth chalcogenides, due to the presence of Kondo effect and reentrant
valence behavior of Ce in cerium chalcogenides. |
