Abstract: | Features of the electronic structure of ternary alloys of the quasibinary Ni3Mn-Ni3Fe and Ni3Mn-Ni3Co systems are discussed on the basis of an analysis of the changes in the absolute thermal emf S and in the conductivity . It is concluded that all the ternary Ni3Mn-Ni3Fe alloys have a closed Fermi surface in both the disordered and ordered states. It is confirmed experimentally that a deep minimum appears on the state-density curve Nd(E) during the ordering of Ni3Mn-Ni3Fe alloys, and the alloy composition whose Fermi surface corresponds to this minimum is given.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii Fizika, No. 8, pp. 126–133, August, 1969. |
