Description
The existence of long range order is shown in the ground state of the two-dimensional isotropic Heisenberg antiferromagnet for S >= 3/2. The method yields also long range order for the ground state of a larger class of anisotropic quantum antiferromagnetic spin systems with or without transverse magnetic fields. (Author)

Mostra-se a existencia da ordem de longo alcance no estado fundamental do anti-ferromagneto de Heisenberg isotropico bidimensional para S >= 3/2. O metodo resulta tambem em ordem de longo alcance para o estado fundamental de uma classe maior de sistemas de spin anti-ferromagneticos quanticos anisotropicos com ou sem campos magneticos transversos.
