In ferroelectric materials the crystal structure distorts, giving rise to a spontaneously formed polarization and electric field. Because of this unique property, ferroelectrics can be found in anything from ultrasound machines and diesel fuel injectors to computer memory. Ferroelectric materials are behind some of the most advanced technology available today. Findings that ferroelectricity can be observed in materials that exhibit other spontaneous transitions, like ferromagnetism, have given rise to a new class of these materials, known as hybrid improper ferroelectrics. The properties of this type of material, however, are still far from being fully understood. New findings published in Applied Physics Letters, help to shine light on these materials and indicate potential for new optoelectronic and storage applications.
