Abstract
The μ+SR were measured on CsMgCl3 single crystals to elucidate the muonium formation and migration in isostructural magnetic halides. More than 60% of incident μ+ were found to form muonium and the fraction of the muonium shows little temperature dependence. A part of muonium located near Mg2+ ions with zero nuclear dipole moments gives a fast relaxing component in the spectra. It was concluded from the decrease of asymmetry and the peak of the relaxation rate of the recovered asymmetry that muonium migrates above 90 K.
