Non-Fermi-Liquid Behavior in Metallic Quasicrystals with Local Magnetic Moments
Non-Fermi-Liquid Behavior in Metallic Quasicrystals with Local Magnetic Moments
Motivated by the intrinsic non-Fermi-liquid behavior observed in the heavy-fermion quasicrystal Au51Al34Yb15, we study the low-temperature behavior of dilute magnetic impurities placed in metallic quasicrystals. We find that a large fraction of the magnetic moments are not quenched down to very low temperatures T, leading to a power-law distribution of …
