Abstract
Electron paramagnetic resonance was measured in Ga1-xMnxAs/GaAs epilayers w
ith 0.002 less than or equal to x less than or equal to 0.01. Data were tak
en as a function of magnetic field orientation at low temperatures. The obs
erved spectra were attributed to ionized Mn acceptor A(-). No neutral Mn ac
ceptor centers were detected. The observed anisotropy of A(-) is interprete
d in terms of sizable demagnetizing fields resulting from ferromagnetic cou
pling between Mn ions. [S0163-1829(99)07235-5].
