Abstract : In this report, results of electron paramagnetic resonance (EPR), electron nuclear double resonance (ENDOR) and x-ray photoelectron spectroscopy (XPS) studies of iron doped, proton implanted indium phosphide will be presented. The EPR spectra were obtained both as a function of sample angle relative to the magnetic field and as a function of temperature at a given orientation. The results obtained in this study again confirm that the environment around the 3+ Fe centers is indeed octahedral. In addition, the EPR spectra indicate that there are defects present that behave very much like a spin glass (magnetically diluted defects present in a material with cooperative interactions between the centers that are most distinctly observable at definite temperatures and magnetic field strengths). These results along with the results from the XPS and ENDOR measurements will be presented and discussed in this report.
