Cobalt-molybdenum (CoMo) thin films: Unveiling structural, electronic, and magnetic insights via experimental and theoretical approaches

Cobalt-Molybdenum (CoMo) thin films were electrodeposited onto silicon surfaces. The properties of these deposits were characterized using X-Ray Diffraction and Scanning Electron Microscopy. Additionally, the structural, elastic, electronic, and magnetic properties of CoMo alloys were investigated through first-principles calculations. The calculated lattice parameters ‘a’ and ‘c’ of CoMo were found to be in excellent agreement with available experimental data. Our calculations indicate that CoMo behaves as a conductor material. Further analysis of the partial density of states of CoMo revealed that the entire valence bands are predominantly composed of d-Co and d-Mo orbitals. Successful determination of the elastic constants C_ij, bulk modulus B, shear modulus G, and Young’s modulus E of CoMo further elucidates its mechanical properties. This comprehensive characterization, combining experimental techniques with theoretical calculations, provides valuable insights into the structural and electronic properties of CoMo, paving the way for their potential applications in various fields.
