We have investigated the spin dynamics of Tb 2Ti 2O 7 as a function of magnetic field applied along the  axis using ac susceptibilty and muon-spin relaxation measurements. We find a significant increase in the imaginary part of the magnetic susceptibility at low fields at our lowest investigated temperature and an increased muon-spin relaxation rate in the same field range persisting to higher temperature. Comparing the data from the two techniques we identify three field regions where the dynamic properties of Tb 2Ti 2O 7 appear to be evolving in different ways with crossovers between the regions at B 1=15 and B 2∼60 mT.
