AbstractUsing both mean field Renormalization group MFRG and Sureface Bulk MFRG SBMFRG we study the critical behaviors of the classical Heisenbergand XY models on simple cubic lattice Critical temperatures as well as critical exponents characterising the universality classesof thesetwo models calculated analytically for 1 2 3 and 4 spin clusters Also by using two Monte Carlosimulation techniques based on metropolis algorithm and single histogram method we calculatecritical temperatures and critical exponents of the classical Heisenbergand XY models for 6 8 12 18 and 27 spin clusters The results are in good agreement with higher accura temethods such asMonte Carlo c expansion and High temperature series p r t I if l V l J 1
