Descrição: The phase diagram and the correlation length exponents of the <math>\pm</math> J D-Vector Spin-Glass model are studied in the framework of the real space mean field renormalization group method. The boundary between the spin-glass (SG) and the ferromagnetic (F) phases is obtained from the renormalization flow equations and shows a reentrant behaviour over the SG region. This re-entrance increases smoothly with the coordination number. Analytical expressions for the thermal and the correlation length exponents are calculated straightforwardly for all fixed points and figures are presented and compared with availables results from other methods and data.
