Abstract
We examine theoretically the possibility of phase separation due to hole ag
gregation in the background of antiferromagnetically ordered CuO2 planes. T
he results which are calculated within a self-consistent mean-held-type app
roximation give obvious evidence of phase separation. Our conclusions agree
with previous numerical results (from exact diagonalization).
