Electronic Structures of the Ferromagnetic Heusler Alloys

Abstract

In order to see the characteristic properties of the ferromagnetic Heusler alloys,the electronic structures of Ni₂MnSn and Pd₂MnSn have been calculated. The common properties of these alloys have been discussed by the present results and those obtained for Cu₂MnAl. The spin polarizations of the constituent atoms are in good are in good agreement with experimental ones. The signs of the spin polarizations of the s-type conduction electrons in the inscribed spheres are consistent with the signs of the measured internal magnetic fields due to the conduction electrons.
