Abstract

A ⁵⁷FeBO₃ single crystal is studied by the nuclear forward scattering (NFS) method. The NFS time spectra from ⁵⁷Fe nuclei are recorded at room temperature under high pressures up to 50 GPa in a diamond anvil cell. In the pressure interval 0 < p < 44 GPa, the magnetic field H^Fe at the ⁵⁷Fe nuclei is found to increase nonlinearly, reaching a maximum value of 48.1 T at p = 44 GPa. As the pressure increases further and reaches the point p = 46 GPa, the field H^Fe abruptly drops to zero, indicating that a transition from the antiferromagnetic to a non-magnetic state occurs in the crystal. In the pressure interval 0 < p < 46 GPa, the magnetic moments of the iron ions lie in the (111) basal plane of the crystal. Several possible mechanisms of magnetic collapse are discussed.
