Abstract

The electronic band-structure calculations of the PdFe ferromagnet and the PdMn antiferromagnet performed in this work permit one to conclude that the specific features of the electrical resistivity observed in the ternary PdMnxFe1−x alloy system [the deviation from the Nordheim-Kurnakov rule ρ0(x)∼x(1−x), which is accompanied by a high maximum of residual resistivity (not typical of metals) ρ 0 m ∼220 µΩ cm at xC∼0.8 and a negative temperature resistivity coefficient in the interval 0.5≤x≤1] are due to the microinhomogeneous (multiphase) state of the alloys and a variation in the band-gap parameter d spectrum caused by antiferromagnetic ordering of a PdMn-type phase.
