Density of States of Co- and Cr-Doped Ni_2.0Mn_1.5Sn_0.5 Heusler Alloys

Abstract:

The composition dependences of the density of states in Co- and Cr-doped Ni-Mn-Sn Heusler alloys are investigated by using first principles calculations. The off-stoichiometric compositions are realized by the coherent-potential approximation. We have shown that the spin polarization decreases with increasing Cr and Co concentrations. While, the total magnetic moment was found to decrease (increase) with increasing Cr (Co) concentration, respectively.
