Description 834-840
The temperature dependent mechanical, thermo-physical and nonlinear ultrasonic properties of europium monopnictides
EuX (X: N, P, As and Sb) were studied in this exploration. The 2nd and 3rdorder elastic constants (SOECs and TOECs) of
EuX were computed with the help of Coulomb and Born-Mayer potential applying two fundamental indicators i.e., the
nearest neighbour distance and the hardness parameter in the temperature span 100-300K. Further the SOECs are applied to
enumerate the mechanical variables such as elastic moduli, Zener anisotropic ratio, Poisson’s ratio and Pugh’s index using
Voigt-Reuss-Hill (VRH) approach at T=300K. The results derived from elastic and mechanical properties confirm the
mechanical stability and brittle nature of EuX. The acoustical velocities have been enumerated using the SOECs and density
of EuX along , and directions at T=300K. All above physical parameters have been utilized to compute
the direction dependent Grüneisen parameter and Debye characteristic temperature of EuX at T=300K. The achieved values
of this exploration are discussed and equated with materials of similar characteristics.
