Abstract
A two-step renormalization group approach - a decimation followed by a mean field renormalization group (MFRG) - is applied for calculations of the critical couplings and critical exponents in two and three dim ensions in the spin-1/2 anisotropic Heisenberg model. The values of th e critical parameters are shown to be in good agreement with the serie s results and are also compared with the results of separate decimatio n or MFRG calculations.
