ODMR and EPR in InP:Mn

Abstract
ESR measurements in InP:Mn show a broad resonance due to Mn2+ with g=2.01 and A=55*10-4 cm-1. Luminescence at 1.15 eV has been investigated by ODMR and a donor resonance at g=1.22, a Mn2+ resonance at g=1.997 and possible hole resonances at g=0.41 and 0.61 are observed. They are discussed in terms of a spin-dependent DAP recombination model involving an exchange interaction between the Mn2+ and a weakly bound hole.
