(a) GaNAs ODMR spectrum taken at 5K and 9.218 GHz. (b) The simulated ODMR curve for the single line of g=2.03. (c) The quadruplet ODMR spectrum after subtracting the curve b from curve a. The simulated ODMR spectrum for the AsGa antisite (d) and for the Gai interstitial (e). The ODMR signals are negative, but are shown here positive for easy viewing.
