The spontaneous magnetization and principal magnetic susceptibilities of TbFeO3 were measured from 4.2 to 300 K. The weak ferromagnetic moment is along the c crystallographic axis in the entire temperature range. The field dependence of the magnetization at 4.2 K was also studied. The magnetic behavior is interpreted in terms of an interaction between the ordered Fe3+ spin system and the electrons occupying the lowest lying "accidental" doublet of the Tb3+ ions. The FeTb interaction and the Tb3+ Van Vl eck susceptibility along the c axis play significant roles in determining the magnetic configuration of the Fe3+ spin system. No indication was found that the TbTb interaction plays a significant role in the magnetic behavior of TbFeO3 at temperature above 4.2 K.
