Electron spin resonance (ESR) has been detected for erbium, Er(4f11), in gallium arsenide. The ESR spectrum was found to be isotropic, with a hyperfine splitting of A(167Er)=208x10 E-4/cm and a g-factor of g=5.921. The magnitude of the latter is compatible with a Gamma 7(Td) ground state, as expected for a substitutional ErGa(4f11):GaAs defect. (IAF)
