Abstract

Resistivity and thermoelectric power (TEP) measurements on CeFe2_2 and two of its pseudo-binaries Ce(Fe, 5% Ir)2_2 and Ce(Fe, 7% Ru)2_2 between 78K and 275K are reported. The resistivity data are analysed in terms of contributions from scattering due to phonon, magnon, spin fluctuation and lattice defects, and also from interband scattering. Attempts are made to analyze the TEP data in terms of these resistivity components. Thermal hysteresis is observed in the temperature dependence of TEP in the Ir and Ru doped CeFe2_2 samples around the ferromagnetic to antiferromagnetic transition, indicating the first order nature of this transition.
