The anisotropic Knight shift of implanted positive muons (micro(+)) in CeB(6) has been studied between 2.2 and 200 K in a field of 0.6 T. The results imply that the field-induced magnetization distribution is not only found at the Ce sites but also in other regions of the unit cell (e.g., near or inside the B6 molecule, as proposed by Saitoh et al. [J. Phys. Soc. Jpn. Suppl. 71, 106-108 (2002)]). While above the antiferroquadrupolar ordering temperature T(Q) approximately 3.55 K this additional magnetization appears to be antiparallel to the Ce moments, a drastic change is observed below T(Q), and the additional magnetization is eventually aligned parallel to the Ce moments.
