Abstract

We have measured the electrical resistivity, Hall coefficient, thermoelectric power, magnetic susceptibility, magnetization, specific heat, magnetoresistance and de Haas-van Alphen (dHvA) oscillation of UPd3 to clarify the magnetic and Fermi surface properties. A phase transition, which occurs at about 4.5 K, is most likely related to the antiferromagnetic ordering because the magnetic specific heat shows a T3 dependence below 2 K. About ten different dHvA branches ranging from 1.8 x 105 Oe to 7.5 x 107 Oe have been observed. From the angular dependence of dHvA frequency, UPd3 is found to consist of the closed spherical Fermi surfaces and multiply-connected ones. The cyclotron masses are light, ranging from 0.5m0 to 3.6m0, which indicate the localized f electron character.
