Effect of anisotropy in the underscreened Kondo lattice
Christopher Thomas, Acirete S. da Rosa Simões, Claudine Lacroix +2
We study the effect of crystal field anisotropy in the underscreened Kondo lattice model. Starting from the two orbital Anderson lattice model and including a local anisotrop…
Application of the S=1 underscreened Anderson lattice model to Kondo uranium and neptunium compounds
Christopher Thomas, Acirete S. da Rosa Simões, J. R. Iglesias +3
Magnetic properties of uranium and neptunium compounds showing the coexistence of Kondo screening effect and ferromagnetic order are investigated within the Anderson lattice Hamilt…
A van Hemmen-Kondo model for disordered strongly correlated electron systems
S. G. Magalhaes, F. M. Zimmer, B. Coqblin
We present here a theoretical model in order to describe the competition between the Kondo effect and the spin glass behavior. The spin glass part of the starting Hamiltonian conta…
A theoretical study of the cluster glass-Kondo-magnetic disordered alloys
F. M. Zimmer, S. G. Magalhães, B. Coqblin
The physics of disordered alloys, such as typically the well known case of CeNi1-xCux alloys, showing an interplay among the Kondo effect, the spin glass state and a magnetic order…
The underscreened Kondo lattice model applied to heavy fermion uranium compounds
N. B. Perkins, M. D. Nunez-Regueiro, B. Coqblin +1
We present theoretical results for the underscreened Kondo lattice model with localized S=1 spins coupled to a conduction band through a Kondo coupling, , and interacting amon…
Doniach diagram for ordered, disordered and underscreened Kondo lattices
B. Coqblin, J. R. Iglesias, N. B. Perkins +2
The Doniach's diagram has been originally proposed to describe the competition between the local Kondo effect and the intersite RKKY interactions in cerium compounds. Here we discu…
