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…

Magnetic excitations in vanadium spinels
N. B. Perkins, O. Sikora
We study magnetic excitations in vanadium spinel oxides AVO (A=Zn, Mg, Cd) using two models: first one is a superexchange model for vanadium S=1 spins, second one includes…

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…
