High-pressure resistivity and thermoelectric power in Yb14MnSb11
We report the electrical transport properties of Yb14MnSb11, resistivity and thermoelectric power under pressures up to 2.3 GPa. In both transport coefficients we can follow the ferromagnetic transition, which shows a shift from the ambient pressure value of 52 K to lower temperatures and eventually saturation at 49 K for p>2.0 GPa. The high values of thermopower and its linear temperature dependence down to 100 K 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.
