چکیده انگلیسی
The anomalous magnetic properties at low temperatures of terbium iron garnet (TbIG) are analyzed and summarized using neutron powder diffraction (NPD) experiments together with high field magnetization, magnetostriction and specific heat measurements performed on single crystals. Reliable information at both microscopic and macroscopic levels is provided about the significant change of the double umbrella structure observed in the NPD results near 54Â K. The positions of the observed maxima at 55-65Â K in the paraprocess magnetic susceptibility along the three mean directions and paraprocess of the forced magnetostriction along the easy axis of magnetization ã111ã agree with the manifestations of the “low-temperature point” TB predicted by Belov at 58Â K. However, the pronounced maximum at 57Â K in the excess of specific heat in zero magnetic fields reveals that the Schottky effect causes anomaly at temperature close the TB point. The results are discussed and compared with previous magnetic, magneto-optical and magnetodielectric reports.
