A study of the electronic structure of Pt3Mn alloys by the LMTO method

The electronic density of states of paramagnetic and ferromagnetic ordered Pt3Mn alloys is calculated using the linear muffin tin orbital method (LMTO) and the atomic sphere approximation (ASA). The Fermi level in the ferromagnetic system is located at the dip valley between two peaks. The magnetic moments on Mn and Pt atoms are 3.64 mu B and 0.22 mu B respectively. These values are close to the experimental ones. The calculated value of the gamma -coefficient is similar to the observed value.
