Abstract

The influence of strain-imposed in-plane lattice symmetry on the structural and magnetic properties of tetragonal-like BiFeO₃ is investigated by x-ray and elastic neutron scattering. We find that an increase in the in-plane distortion results in an increase of the Néel temperature from 313 ± 5 K to 324 ± 3 K for films grown on YAlO₃ and LaAlO₃, respectively. The change in magnetic ordering temperature is reproduced in three-dimensional Heisenberg Monte-Carlo simulations. These results show that strain cannot be treated as a single scalar number or simply as a direct consequence of the lattice mismatch between the film material and the substrate.
