Abstract
Resistivity, Hall resistivity, thermopower, thermal conductivity, and magnetization are reported for polycrystalline Ba8Ni5Ge41. Ba8Ni5Ge41 is diamagnetic with susceptibility χ dia = (−2.4 to −2.82) × 10−7 emu/g. Semiconductor-like behavior was observed for the resistivity. The thermopower shows positive values for a wide temperature range. The Hall resistivity indicates the dominance of electrons, suggesting the existence of multiband conductance. At room temperature, the thermal conductivity is 1.78(5) W/K m. The highest ZT of Ba8Ni5Ge41 is 0.0016 at about 278 K.
