EuPd3, which is in the trivalent (Eu3+) electronic state, is a rare compound because most Eu compounds are in the divalent (Eu2+) electronic state and order magnetically. The electronic state of EuPd3 was previously studied by Mössbauer, magnetic susceptibility, and X-ray absorption experiments using polycrystalline samples. We succeeded in growing single crystals of EuPd3 by the Bridgeman method and carried out a de Haas-van Alphen (dHvA) experiment. The dHvA branches detected in EuPd3 are well explained by the results of the full potential linear augmented plane wave (FLAPW) energy band calculation based on a local density approximation (LDA) with additional treatments for EuPd3, revealing the trivalent electronic state. Conduction electrons are mainly Pd-4d electrons. The cyclotron effective masses are determined from the temperature dependence of the dHvA amplitude, ranging from 0.3 to 1.0m0 (m0: rest mass of an electron), which are also consistent with the corresponding band masses.
