We report synchrotron radiation diffraction and muon spin rotation (μSR) measurements on the frustrated pyrochlore magnet Tb₂Ti₂O7. The powder diffraction study of a crushed crystal fragment does not reveal any structural change down to 4 K. The μSR measurements performed at 20 mK on a mosaic of single crystals with an external magnetic field applied along a three-fold axis are consistent with published a.c. magnetic-susceptibility measurements at 16 mK. While an inflection point could be present around an internal field intensity slightly above 0.3 T, the data barely support the presence of a magnetization plateau.
