Organic ammonium modulated mixed-valence multiferroics exhibiting large spontaneous strain and exchange bias
Three isotopological (stb) mixed-valence iron-formate frameworks, [A][Fe<sup>III</sup>(Fe<sup>II</sup>)<sub>2</sub>(HCOO)<sub>9</sub>] (1-3), were constructed and exhibit ferroelastic phase transition with spontaneous strain of 0.16. 1-3 are spin-canted antiferromagnets with distinct <i>T</i><sub>N</sub> from 26 K to 36 K and display exchange bias (EB) performance induced by the pinning of the spins at distinct sublattices.
