Electronic Structure of Pt$\text{}_{1-x}$Mn$\text{}_{x}$ and Pt$\text{}_{1-x}$Cr$\text{}_{x}$ Disordered Alloys

Electronic density of states of disordered fcc Pt$\text{}_{1-x}$Mn$\text{}_{x}$ and Pt$\text{}_{1-x}$Cr$\text{}_{x}$ alloys for 0 < x < 0.35 is calculated by the tight-binding linear muffin-tin orbital (TB LMTO) and the coherent potential approximation (CPA) method. Using the Stoner model it was found that the disordered Pt-Mn and Pt-Cr alloys are paramagnetic
