Abstract

We have measured the electrical resistivity, magnetic susceptibility, high-field magnetization, specific heat and de Haas-van Alphen (dHvA) oscillation of Ce2RhIn8, together with the dHvA oscillation of La2RhIn8. In La2RhIn8 we detected three kinds of dHvA branches showing cylindrical Fermi surfaces, which are well explained by the result of FLAPW energy band calculations. The corresponding two dHvA branches were detected in Ce2RhIn8, indicating that the topology of the Fermi surface in Ce2RhIn 8 is approximately the same as that of La2RhIn 8. The magnetic susceptibility and magnetization of Ce 2RhIn8 were analyzed on the basis of the crystalline electric field scheme of localized-4f energy levels. Pressure-induced superconductivity was confirmed above 1.2 GPa from the resistivity and ac-susceptibility measurements.
