We have used a self-consistent Green's function theory based on the quasi-two-dimensional Heisenberg model to explain the magnetic correlation length for both undoped and lightly doped samples of La[sub 2]CuO[sub 4[minus][ital y]]. Our analytical expression gives an exponential decay of correlation length with temperature and it includes the effect of doping through its dependence over the interlayer coupling. We have compared our numerical calculations with experimental results for magnetic correlation length in both undoped and lightly doped samples of La[sub 2]CuO[sub 4[minus][ital y]]. Our results are in excellent agreement with experimental results up to 900 K for the undoped compound.
