Abstract Spontaneous and by an external magnetic field induced magnetic phase transitions in TbFeO 3 have been experimentally studied. Precision investigations of velocities of transmission and attenuation of sound wave were made, the processes of formation and rearrangement of magnetic structure examined and its change under the influence of external magnetic field explored. This has been made possible by the development of methods of controlled growth of rare‐earth orthoferrites resulting in the formation of high‐quality single crystals of required size with reproducible physical properties. The measurements were taken in the temperature range from 0.45 to 8.0 K. From the threshold Geld values a H a T phase diagram for TbFeO 3 has been plotted.
