Non Local Interaction in the Kondo Lattice
A Kondo lattice has been obtained applying the Schrieffer-Wolff transformation [I] on an Anderson lattice, keeping the term corresponding to non-local Kondo interaction. Using the Integral Functional method, proposed by Lacroix and Cyrot [2], we study the influence of that interaction on the phase diagram of the Kondo lattice, restricted to the nearest neighbour case. Introduction H* = Jl C ( f...

متن کاملNuclear magnetic resonance in Kondo lattice systems.
Nuclear magnetic resonance has emerged as a vital tool to explore the fundamental physics of Kondo lattice systems. Because nuclear spins experience two different hyperfine couplings to the itinerant conduction electrons and to the local f moments, the Knight shift can probe multiple types of spin correlations that are not accessible via other techniques. The Knight shift provides direct inform...
متن کاملYbNiSi3: An antiferromagnetic Kondo lattice with strong exchange interaction
We report on the structural, thermodynamic, and transport properties of high quality single crystals of YbNiSi3 grown by the flux method. This compound crystallizes in the SmNiGe3 layered structure type of the Cmmm space group. The general physical behavior is that of a Kondo lattice showing an antiferromagnetic ground state below TN=5.1 K. This is among the highest ordering temperatures for a ...
متن کاملSpin Glass and antiferromagnetism in Kondo-lattice disordered systems
Abstract. The competition between spin glass (SG), antiferromagnetism (AF) and Kondo effect is studied here in a model which consists of two Kondo sublattices with a gaussian random interaction between spins in differents sublattices with an antiferromagnetic mean Jo and standard deviation J . In the present approach there is no hopping of the conduction electrons between the sublattices and on...
