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//m//a//x increases as t//m//a//x approximately (T minus T//f)** minus **6 exp left bracket C(T minus T//f)** minus **1**/**4 right bracket . For the Heisenberg spins t//m//a//x approximately (T minus T//f)** minus **1**0**. **5. It is shown that the inclusion of weak random-anisotropy exchange leads to the Ising asymptotics for t//m//a//x in the Heisenberg spin glass.
