Abstract
To elucidate the nature of transport mechanism below Curie temperature TC, we have analyzed the temperature dependence of resistivity (ρ) and thermopower (S) of metallic La1−xSrxCoO3 (0.30≤x≤0.50). At low temperature well below TC both ρ and s exhibit T2 behavior whereas over a temperature interval just below TC, they show a T4 dependence due to the scattering of charge carriers by magnetic fluctuations. These fluctuations can be suppressed by a magnetic field, leading to a negative bulk magnetoresistance in cobaltates and in other itinerant ferromagnets such as manganites and CrO2.
