Single crystals of the multiferroic rare earth orthoferrite TbFeO3 have been grown by means of the optical floating zone method. Using measurements of the magnetization, ac susceptibility and specific heat we have studied the complex, anisotropic magnetic phase diagram of TbFeO3 for magnetic fields up to 9 T applied along all three major crystallographic axes. In particular, our findings may help to shed light on the nature and origin of the various magnetic phase transition and crossovers observed as a function of magnetic field and temperature.
