Spin Glass and antiferromagnetism in Kondo lattice disordered systems
S. G. Magalhaes, A. A. Schmidt, F. M. Zimmer +2
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 interact…

Spin Glass and Ferromagnetism in Kondo lattices compounds
S. G. Magalhaes, A. A. Schmidt, Alba Theumann +1
The Kondo lattice model has been analyzed in the presence of a random inter-site interaction among localized spins with non zero mean Jo and standard deviation J. Following the sam…

The Ising spin glass in a transverse field. Results of two fermionic models
A Theumann, A A Schmidt, S G Magalhaes
We analyze the long range Ising spin glass in a transverse field by using Grassmann variables in a field theory where the spin operators are represented by bilinear combinations of…
