Mechanism for stabilization of a spin liquid in a Kondo lattice
Kikoin K. A., Kiselev M. N., Mishchenko A. S.
A mechanism is proposed for stabilization of a spin liquid of neutral fermions in a Kondo lattice. A single-site Kondo scattering of conduction electrons at temperatures Τ above the Kondo temperature TK not only suppresses the antiferromagnetic order but also promotes the onset of an RVB state. The Kondo scattering "freezes" at T*>TK. In the limit T—>0, the system thus behaves as a two-component Fermi liquid with neutral and charged components. © 1994 American Institute of Physics.
