Oe. The experimental results are compared to the dHvA results of CeIn
under pressure of 2.7 GPa, together with the results of energy band calculations.

Times Cited Count:11 Percentile:55.17(Physics, Multidisciplinary)We have succeeded in growing a high-quality single crystal of ThIn with the cubic structure by the In-flux method and measured the electrical resistivity, magnetic susceptibility and de Haas-van Alphen (dHvA) effect. Several dHvA branches were observed, ranging from 5.2

Oe. The Fermi surface consists of a nearly spherical Fermi surface and a multiply-connected Fermi surface with many but small extremal cross-sections. The corresponding cyclotron effective masses are small, ranging from 0.31 to 1.4
. These Fermi surface properties are well explained by the energy band calculations based on the FLAPW method.

Times Cited Count:25 Percentile:72.52(Physics, Multidisciplinary)We observed for the first time the de Haas-van Alphen oscillation in a paramagnet PuIn. One detected dHvA branch named
corresponds to a closed band-27 electron Fermi surface, where three kinds of closed Fermi surfaces are calculated on the basis of the 5
-itinerant band model. The cyclotron mass of branch
was determined as 4.8
. The dHvA signals are found to be extremely reduced as a function of time due to point defects produced by
-decay of
Pu.
