Magnetothermal Transport-properties of Granular Co-ag Solids

Primary tabs

Piraux, Luc [UCL] Cassart, M. Jiang, JS. Xiao, JQ. Chien, CL.

Thermal conductivity and thermoelectric power have been measured between 2 K and 300 K on granular Co20Ag80 solids. As in ordinary metals, thermal conductivity is largely dominated by the electronic contribution. The Wiedemann-Franz law is found to be satisfied over the whole temperature range investigated, which is mainly ascribed to dominant large-angle elastic scattering processes. Giant magnetothermal conductivity has been observed in accordance with the giant magnetoresistance effect. The magnetothermoelectric power is negative and increases with temperature.
