Study of Certain Features of the Electronic Structure of the Ternary Alloys NI2(Mn, Fe) and NI3(Mn, CO)

摘要

The changes in electronic structure related to transport processes occurring during the alloying of the alloy Ni3Mn with iron and cobalt, and the ordering of the ternary alloys thus formed are presented. The Hall effect, the absolute thermal emf, the internal saturation induction, the Nernst-Ettingshausen constant, and the electrical resistivity were measured. Results show a decrease in the contribution of hole sections of the Fermi surface to the transport process occurs together with a considerable increase in the contribution of electron sections. In this case, the mobility of 3 dimensional holes decreases and the mobility of 4s electrons increases considerably.
