Abstract
We report the electrical transport properties of , resistivity and thermoelectric power under pressures up to . In both transport coefficients we can follow the ferromagnetic transition, which shows a shift from the ambient pressure value of to lower temperatures and eventually saturation at for . The high values of thermopower and its linear temperature dependence down to demonstrate that the system is a bad metal. Anomalies in the thermopower below the ferromagnetic transition are rather sensitive to pressure. Our experimental observations are consistent with the model of an underscreened Kondo lattice.
