Neutron diffraction experiments of TmFeO3 single crystals were performed in the external magnetic fields. The field along the 𝑐 axis increases temperature of spin-reorientation transition 𝑇SR from phase Γ⁢4 to Γ⁢2 . Application of the field along 𝑏 axis led to the decrease of 𝑇SR and to the formation of new phases. Based on the temperature and field dependence of the Bragg reflection intensity, the configuration of magnetically induced phases was proposed.
