Magnetic, Electronic, and Mechanical Properties of Strongly Correlated Samarium Mono-chalcogenides under High Pressure

DySb under high pressures: A full-potential study

“…The calculated values of the phase transition pressure (PT in GPa), the % volume collapse at PT ( V(PT)/V(0)), energy of structures at zero pressure with respect to the rock-salt phase ( G in Ry/unit cell/atom) and the equilibrium volume (V0 inÅ 3 puted various combinations of these second-order elastic constants viz., shear and stiffness constant (C S and C L ), isotropic shear (G), Young's (Y) moduli, Kleinman parameter ( ), Poisson's ratio ( ), elastic anisotropy factor (A) and Cauchy's relation at ambient conditions by using the relations and conditions listed elsewhere [8].…”

“…In recent years, the rare-earth (RE) compounds with rock-salt structure have drawn considerable interests of materials scientists due to their diverse structural, transport, magnetic and vibrational properties [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Spurred by the search for magnetic semiconductors i.e., spintronic materials, we now have a better understanding of the electronic, magnetic and transport properties of RE compounds which are, generally, semiconductors or semimetals.…”
