Vp. Glazkov et al., Neutron diffraction evidence for the spin-reorientational transition in FeBO3 at high pressures, JETP LETTER, 71(4), 2000, pp. 165-166
The spin-reorientational transition from the state with "easy-plane" anisot
ropy to the state with "easy-axis" anisotropy-a pressure analogue of the Mo
rin temperature transition in hematite-was detected in iron borate at a pre
ssure of P similar to 17 kbar at room temperature by the neutron diffractio
n method. (C) 2000 MAIK "Nauka/Interperiodica".
