Abstract

We have studied Fermi surface properties of LaRhIn5 and CeTIn5 (T: Co, Rh and Ir) via the de Haasvan Alphen (dHvA) experiment. The Fermi surface of a non-4f reference compound LaRhIn5 is quasitwo dimensional, reflecting the unique tetragonal crystal structure, which is consistent with the result of FLAWP energy band calculations. The Fermi surface of an antiferromagnet CeRhIn5 is similar to that of LaRhIn5, although the cyclotron mass in CeRhIn5 is roughly by one order larger than that in LaRhIn5. Both Fermi surfaces are, however, different from those of CeCoIn5 and CeIrIn5 which are well explained by the 4f-itinerant band model. The 4f electrons in CeRhIn5 thus do not contribute to the volume of the Fermi surface. We have also studied magnetic and superconducting properties of CeCoIn5 and CeIrIn5.
