Abstract:
A $^{57}$FeBO$_3$ single crystal is studied by the nuclear forward scattering (NFS) method. The NFS time spectra from $^{57}$Fe 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 $^{57}$Fe nuclei is found to increase nonlinearly, reaching a maximum value of $481$ 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.
