Abstract
Spontaneous and by an external magnetic field induced magnetic phase t ransitions in TbFeO3 have been experimentally studied. Precision inves tigations of velocities of transmission and attenuation of sound wave were made, the processes of formation and rearrangement of magnetic st ructure examined and its change under the influence of external magnet ic field explored. This has been made possible by the development of m ethods of controlled growth of rare-earth orthoferrites resulting in t he formation of high-quality single crystals of required size with rep roducible physical properties. The measurements were taken in the temp erature range from 0.45 to 8.0 K. From the threshold field values a H- a - T phase diagram for TbFeO3 has been plotted.
