A new method for calculating the thermodynamic and physical properties of compounds: Application to Laves phase Fe2Mo

The thermodynamic and physical properties of the Laves phase Fe2Mo have been investigated using the finite-temperature quantum mechanical calculations within the frame of the density functional theory (DFT). All relevant free energy contributions including electronic, vibrational and magnetic excitations are considered. The quasi-harmonic Debye - Gruneisen theory is used. In this work, a new method of searching a thermal expansion path of...
