Abstract

Calculations of energy spectra of isostructural antiferromagnetic PdMn and ferromagnetic PdFe were performed using the linearized muffin-tin orbital (LMTO) method. Optical and electrical properties of the compounds were measured. It was shown that an energy "pseudogap" is formed in the energy spectrum of PdMn upon antiferromagnetic ordering. According to the band calculations, the "pseudogap" width ΔE is equal to ∼ 1 eV. The formation of the "pseudogap" leads to a 20-fold decrease in the density of electron states at the Fermi level in comparison with that of the nonmagnetic state.
