The de Haas-van Alphen (DHVA) effect of the stage-1 AlCl3 graphite intercalation compound has been studied in the temperature range from 1.5 K to 4.2 K with magnetic fields of 2.5 to 5 T. There is a dominant oscillation with a frequency of 1250 T with the magnetic field parallel to the c axis, which corresponds to an extremal cross sectional Fermi surface area of 0.119 AA-2. The charge transfer per C atom is 0.032e+. The cyclotron mass is (0.261+or-0.001) m0. The Fermi energy determined from the Holzwarth band model is -1.14 eV. No bearing of the dominant frequency is observed in the 2.5 to 5 T field range, which indicates little undulation of the Fermi surface along the c axis. The Dingle temperature TD of one sample is (3.1+or-0.2) K, which corresponds to a mean free path lD of (4.8+or-0.4)*103 AA.

The electrical resistivity, Hall effect, and magnetic susceptibility of single-crystal UPd2Si2 have been studied between 4.2 and 300 K. A large anisotropy was observed in both the magnetic and transportproperties. There is a quadratic temperature dependence of the resistivity for a range of temperatures between 4.2 and 80 K. At higher temperatures, the resistivity indicates a Kondo-type behavior. The behavior of these quantities is accounted for by the magnetic phase transitions at 108 and 136 K reported from neutron-scattering studies. At high temperatures, the magnetic susceptibility of UPd, Si~is Curie-Wiess-like along the c axis. The temperature dependence of the Hall coefficient above 108 K is accounted for by a theoretical model invoking skew scattering of conduction electrons by localized magnetic moments.
