Abstract

The low-temperature (1.8 ≤ T ≤ 30 K) heat capacity of microscopically inhomogeneous PdMnxFe1 − x alloys in the region of the transition between the ferromagnetic, atomically ordered state of the PdFe alloy and the antiferromagnetic intermetallic state of the PdMn compound was studied. Theoretical calculations of the electronic band structure were found to agree with experimental data on the low-temperature heat capacity of the alloys. Possible reasons for the anomalous behavior of the electronic properties (electrical resistivity, ordinary Hall effect, thermopower, electronic heat capacity) at nucleation of the low-Ohmic (ρ0 < 8 μΩ cm) PdFe-type phase in the high-Ohmic (ρ0 < 100 μΩ cm) PdMn-type matrix at xC2 ∼ 0.8 are discussed.
