We explore novel materials’ properties resulting from the conversion of ferroic states by combining multiple ferroic states classified according to the breaking of various symmetries, such as time reversal, space inversion, rotation, and mirror symmetries. We term such conversion “multiferroic conversion“. Through approaches such as materials design and development based on the multiferroic conversion and experimental demonstrations of the conversion by external perturbations, we establish the concept of multiferroic conversion which ties seemingly unrelated ordered states, and manifests new materials’ properties by freely converting the ferroic state.
