摘要：

We solve the SU(N) Heisenberg spin-glass model in the limit of large N focusing on the small temperature behaviour of the specific heat C-nu within the spin-glass phase. We consider the influence of the quantum fluctuations and observe that when they are strong the low T behaviour is quadratic. As quantum fluctuations decrease for large values of S, a broad maximum appears in the C-nu(T)/T curve.
