Özet

To understand the electronic structure of the heavy fermion superconductors CeMIn5, we have performed a comprehensive magnetic study of these materials.(1-4) Our quantum oscillation studies reveal that the Fermi surface becomes systematically more 2-d (and displays heavier effective masses) as one progresses from M=Rh to M=Ir to M=Co, consistent with the observed increase in superconducting T-c. Furthermore, dilution studies show that the f-electrons in CeRhIn5 are substantially localized whereas in CeIrIn5 and CeCoIn5 a more itinerant character is observed.
