Ferroelectrics and multiferroics articles from across Nature Portfolio

Ferroelectrics and multiferroics are a class of materials that exhibit switching of their physical properties under an external influence. Ferroelectrics demonstrate a switchable electric polarization when an electric field is applied. Multiferroics exhibit a similar ‘ferroic’ behaviour in two or more of their (usually electric, magnetic or elastic) properties.

    The output mechanical energy densities of ferroelectric polymers remain orders of magnitude smaller than those of piezoelectric ceramics and crystals, limiting their applications in soft actuators. But polymer composites subject to an electro-thermally driven ferroelectric phase transition under low electric fields are now shown to have giant actuation strains and large energy densities.

    High-performance ferroelectric materials are used in many applications, ranging from actuators to capacitors. Now, high entropy is emerging as an effective and flexible strategy for enhancing the physical properties of ferroelectrics via the delicate design of local polarization configurations.

    When BiFeO3 layers are confined between TbScO3 layers in an epitaxial superlattice, crystallographically orthogonal voltages can induce reversible, non-volatile switching between polar and antipolar states in BiFeO3. This symmetry switch also leads to marked changes in the nonlinear optical response, piezoresponse and resistivity of the system.
