  The spin state of holes bound to Mn acceptors in GaMnAs is investigated by
optical spectroscopy. Concentrations of Mn from 10^17 to 10^19 cm^-3 were
studied as a function of magnetic field and temperature. The photoluminescence
from recombination of electrons with holes bound in the Mn-acceptor complex
(MAC) displays multiple spectral peaks. The circular polarization rho of these
peaks increases with increasing magnetic field and saturates at rho ~= 1/3.
This value of polarization is expected from modeling the addition of spin
angular momentum and interband optical transition matrix elements.
