A quantum critical behavior of the magnetic susceptibility was observed in aquasicrystal containing ytterbium. At the same time, a mixed-valence feature ofYb ions was reported, which appears to be incompatible with the magneticinstability. We derive the magnetic susceptibility by expressing thequasiperiodicity as the distributed hybridization strength between Yb 4f andconduction electrons. Assuming a wide distribution of the hybridizationstrength, the most f electrons behave as renormalized paramagnetic states inthe Kondo or mixed-valence regime, but a small number of f moments remainunscreened. As a result, the bulk magnetic susceptibility exhibits a nontrivialpower-law-like behavior, while the average f-electron occupation is that ofmixed-valence systems. This model thus resolves two contradictory properties ofYb quasicrystals.
