The PIn antisite centre has been observed in electron-irradiated InP by monitoring the magnetic circular dichroism at 0.95 mu m (1.3 eV). A direct comparison of the EPR and the MDC-ODMR results shows that the optical method is approximately 100 times more sensitive. A new broad resonance with g=1.93+or-0.01, Delta B=75 mT which may be due to vacancies has been observed via an absorption at 1.08 mu m (1.15 eV). The PIn resonances have not been observed in undoped InP.
