Special Issue Information

Dear Colleagues,

Representing a quantum leap in the semiconductor industry, ferroelectric materials have been widely used in applications such as memory devices, field-effect transistors, and micro-actuators due to their intrinsic hysteresis behaviour and electrically switchable nature, and researchers have recently been making progress in discovering new ferroelectric materials and new ferroelectricity mechanisms. Nevertheless, there are still open questions closely related to the application of ferroelectric materials, which are drawing great research interest. For instance, how do defects in real materials influence ferroelectric performance, and can we control the defect level by the choice of synthesis technique? In newly discovered ferroelectric materials, can the ferroelectricity be efficiently coupled with other controllable parameters? What happens if ferroelectrics are applied at low dimensions?

The present Special issue on “Multifunctionalities in Advanced Ferroelectric Materials” aims to publish papers providing a scientific illustration of the design and synthesis of (potential) ferroelectric materials; analyses of microscopic structure and texture; characterizations of phononic, photonic, and electronic phenomena; and demonstrations of prototypical devices and application perspectives. The Issue will summarize the recent progress on functional ferroelectric materials and provide insights into the future study of next-generation ferroelectric materials and ferroelectric-based devices.

Triangular lattice magnets have attracted extensive research interest because they are potential hosts for geometrically frustrated magnetism and strong quantum fluctuations. Here, utilizing a laser floating zone technique, we report the first-time successful growth of a DyInO3 sizable crystal, which contains Dy3+-based triangular layers. The fine-tuning of Indium stoichiometry was found to be the key factor in the stabilization of the desired hexagonal phase. The X-ray diffraction study of the crystal structure reveals a non-centrosymmetric P63mc space group. Switchable polarization, i.e., ferroelectricity, and ferroelectric domain configuration are experimentally demonstrated at room temperature. Anisotropic magnetic and thermodynamic measurements unveil antiferromagnetic interactions, the absence of long-range ordering down to 0.1 K, and a possible doublet ground state, indicating a strongly frustrated magnetism. Our findings suggest that the DyInO3 crystal is an excellent platform for studying emergent phenomena and their interplay with coherent topological defects in the quantum realm. Full article
