Abstract:

The optical properties of PdMnxFe1-x ternary alloys in the homogeneous ferromagnetic (F-1, for xsimilar to0) and antiferromagnetic (A, for xsimilar to1) states, as well as in the microinhomogeneous state (at x=0.7), are discussed. In the x=0.7 alloy, the presence of nuclei of the low-resistivity, PdFe-type F-1 phase in the high-resistivity, PdMn-type A matrix was shown to produce a narrow maximum on the optical-conductivity sigma(omega) curve at Esimilar to0.1 eV, which is due to a geometric resonance associated with light scattering from phase inhomogeneities of the sample. The behavior of sigma(omega) in the interband transition region is dominated by parameters of the electronic spectrum of both the A and F-1 phases. (C) 2003 MAIK ``Nauka/Interperiodica{''}.
