Magnetic state of the intermetallic TbMn6Sn6 compound was studied by neutro
n diffraction analysis in external magnetic fields of H = 0, 4, and 5 kOe.
Magnetic moments and their orientations were determined for the Tb and Mn s
ublattices. Magnetic fields higher than 4 kOe were shown to induce spin-reo
rientational transition at room temperature from the c axis to the basal pl
ane. (C) 2000 MAIK "Nauka/ Interperiodica".
