The electronic g-factor anisotropy determined from measurements near the magic field of anomalous muonium in silicon and germanium

Abstract

The field dependences of the anomalous muonium μSR frequencies have been measured in Si and Ge around the "magic field". The results show a clear electronic g-factor anisotropy exists for Ge with g|-g1=0.033, while that of Si is much smaller and essentially zero within the experimental accuracy. © 1984 J.C.
