摘要：
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 rho(0) (x) similar to x (1 - x), which is accompanied by a high maximum of residual resistivity (not typical of metals) rho(0)(m) similar to 220 muOmega cm at x(C) similar to 0.8 and a negative temperature resistivity coefficient in the interval 0.5 less than or equal to x less than or equal to 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.
