Estudo de interações competitivas e anisotropia em sistemas magnéticos
=== We studied the efect of competitive interactions and anisotropies in the Heisenberg model in diferent situations. Initially, we treat the antiferromagnetic Heisenberg model of spin S = 1 with competitive interactions between next J1 and next-nearest J2 neighbors (Heisenberg model J1 J2) and ea...
