Thermoelectric and thermogalvanomagnetic properties of NiBi3

We present some results of an experimental study on transport properties of poly-crystalline NiBi3. Resistivity, thermoelectric power and the Nernst c oefficient were measured in a magnetic field up to 1.2T between 100 and 300 K. A large magnetoresistance was observed and it was revealed that the beh avior of thermoelectric power changed markedly upon the application of a ma gnetic field. The carrier mobility was determined to be 0.446 m(2)V(-1)s(-1 ) at room temperature and the Fermi energy was estimated to be 0.643 eV. We obtained an expression rho = rho (0) + d(H) exp(-(T-0(H)/T)(1.36H2+1)) as the temperature and magnetic field dependence of resistivity.
