抄録

The thermoelectric properties of Mn and Ni substituted sintered magnetite (Mn<sub>2/3</sub>Ni<sub>1/3</sub>)<sub>x</sub>Fe<sub>3-x</sub>O<sub>4</sub> were investigated for x=0, 0.4, 0.8 and 1.2 in the temperature range 100-700°C. It was found that the grain boundary didn't affect the electrical conduction notably in this material. The thermoelectric power factor increased with increasing the temperature for each x, and marked a maximum value of 1.31 μW/K<sup>2</sup>cm for x=0.4 at 700°C.
