Abstract
We present some results of an experimental study on transport properties of poly-crystalline NiBi3. Resistivity, thermoelectric power and the Nernst coefficient were measured in a magnetic field up to 1.2 T between 100 and 300 K. A large magnetoresistance was observed and it was revealed that the behavior of thermoelectric power changed markedly upon the application of a magnetic field. The carrier mobility was determined to be 0.446 m2V-1s-1 at room temperature and the Fermi energy was estimated to be 0.643 eV. We obtained an expression ρ= ρ0 + d(H) exp (-(T0(H) / T)1.36H2+1) as the temperature and magnetic field dependence of resistivity.
