Abstract
Neutron diffraction is used to show that small (7 MPa, or 70 bar) uniaxial pressure produces significant changes in the populations of magnetic domains in a single crystal of 2% Nd-doped bismuth ferrite. The magnetic easy plane of the domains converted by the pressure is rotated 60° relative to its orginal position. These results deomonstrate extreme sensitivity of the magnetic properties of multiferroic bismuth ferrite to tiny (less than 10-4) elastic strain, as well as weakness of the forces pinning the domain walls between the cycloidal magnetic domains in this material.Citation
