Description 570-575
The pseudo ab initio ability is based on density function theory (DFT), use of generalized gradient approximation (GGA). In this work we use the Siesta code for the first time in studying this specific FeNi3 and FeNi2Pt alloys and its fcc phase which enabled us to find the structural and optical properties of FeNi3 and FeNi2Pt alloys in its fcc cubic crystal structure. Obtained results showed that the structural properties of the cubic phase structure have lattice constants very close to what was previously found in theoretical and experimental studies, and all the optical properties calculated such as absorption coefficient, reflectivity, refractive index, and the imaginary part of the dielectric constant, show that the FeNi3 and FeNi2Pt alloys They are two electrical conductors, whose valence band is completely overlapped with the conduction band. Through the optical results, it was found that we can use them in the infrared and visible region applications, and this type of work was studied in this research for the first time.
