Calculation of the structure properties of the cubic phase of using Full Potential Linearized Augmented Plane wave (FP-LAPW) method

In this paper,the structural properties(such as lattice constant,bulk modulus,compressibility,...)of cubic phase were theoretically investigated.The calculations have been performed using a Full Potential Linearized Augmented Plane wave (FP-LAPW) method in the framework of density functional theory(DFT) with various Approximations using Wien2k package.The obtained results show that using GGA96 with spin effects is in a better agreement with other theoretical approximations.Besides,density of electronic states has beenstudied in cubic .The results show that,there is a strong covalent band between O-O,Cr-Oand La-O.These results are in good agreement with the published theoretical and experimental data.
