Multiferroic Y(Lu)MnO3 undergoes an isostructural transition at the magnetic Neel transition, producing giant atomic displacement for every atom in the unit cell. It appears that this happens without either soft-mode degrees of freedom or orbital degrees of freedom. This extremely large magneto-elastic coupling is unprecedented - larger by two orders of magnitude than in any magnetic materials.
