Superconductivity in the Kondo lattice: a mean-field approach
M. A. Gusmao, A. A. Aligia
We calculate the superconducting critical temperature T_c and the Kondo temperature T_K of the Kondo lattice, decoupling the Kondo exchange interaction in the unrestricted Hartree-…

Metamagnetism in one dimensional systems with edge sharing CuO polihedra
A. A. Aligia
We study a Heisenberg chain with nearest-neighbor (NN) J1 and next-NN J2 exchange interactions with anisotropies Delta_1 and Delta_2 respectively. We investigate by analytical and…
