Sa. Guretskii et al., LOW-TEMPERATURE MAGNETIC-PROPERTIES OF TERBIUM ORTHOFERRITE SINGLE-CRYSTALS, Crystal research and technology, 31(7), 1996, pp. 897-902
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.
