Effect of Cd Doping on Mechanical Properties of SrCoO₃

Abstract:

We have investigated the elastic and thermal properties of Sr_1-xCd_xCoO₃ (0=x=0.1) probably for the first time by means of modified rigid ion model (MRIM). In this paper, we present the second order elastic constants (SOECs) and other elastic properties like Bulk modulus (B), Young's modulus (Y), Shear modulus (G), ̠̹̿̓̓̿̾˷̓˰̱̹͂̈́̿˰˸σ˹˼˰̵̜̱̽˷̓˰̵̵̱̱̀͂̽̈́͂˰˸m, l), transverse, longitudinal, ˰̵̷̵̱̱͆͂˰̵͇̱͆˰̵̼̳̹͉͆̿̈́˰˰˸υ_t, υ_l˼˰υ_m) and Anisotropy parameter (A). Here, the SOECs for Sr_1-xCd_xCoO₃ compounds are positive and satisfy the generalized criteria for mechanically stable crystals: (C₁₁-C₁₂) > 0, (C₁₁+2C₁₂) > 0 and C₄₄ > 0 which confirm that Sr_1-xCd_xCoO₃ (0=x=0.1) belong to metallically bonding materials.
