Abstract
Zero and longitudinal field mu SR have been used to examine the single t ground state magnetism of the diluted magnetic semiconductor Hg1-xFe xSe. For x greater than or equal to 0.05 mu SR experiments indicate sp in glass behaviour which is limited to sample regions with locally enh anced Fe2+ content. Longitudinal field spectra in the glassy state rev eal a static local field similar to 50 mT due to induced moments of Fe 2+. These are proposed to originate from a distribution of bound magne tic polaron energies.
