| Popis: |
The evolution of the band-structure parameters of Ce1−xYbxCoIn5 was studied as a function of Yb doping by systematic de Haas–van Alphen (dHvA) measurements. We found only a small change of the dHvA frequencies and effective masses of CeCoIn5 for a low Yb concentrations (x =0.1). A drastic change of the Fermi surface appears for high dilution, i.e., for x ≥0.55. The experimentally observed Fermisurface topology of YbCoIn5 is in perfect agreement with the calculated band structure. For small x, the effective masses remain strongly renormalized, whereas for ≥0.55 the masses are reduced dramatically. |
