Abstract
The analytical theory of slow relaxation of the Ising and vector 3-D spin glasses with the finite range interaction near the freezing transition point T f has been developed. In the Ising case, the maximum relaxation time t max increases as t max ∼(T−T f ) −6 exp[C(T−T f ) −1/4 ]. For the Heisenberg spins t max ∼(T−T f ) −10.5 . It is shown that the inclusion of weak random-anisotropy exchange leads to the Ising asymptotics for t max in the Heisenberg spin glass Theorie analytique de la relaxation lente des verres de spin 3D vectoriels et de ceux d'Ising avec interaction de portee finie pres du point de transition de gel. Croissance du temps maximal de relaxation suivant (T-T f ) −6 exp(C(T−T f ) −1/4 ) dans le cas d'Ising et suivant (T−T f ) −10,5 dans le cas de Heisenberg. Par inclusion de l'echange d'anisotropie faible aleatoire, obtention d'un comportement asymptotique d'Ising pour les verres de spin d'Heisenberg
