A single phase four-layer Aurivillius structured ferroelectric ceramic, (Ca0.2Sr0.2Ba0.2Pb0.2Nd0.1Na0.1)Bi4Ti4O15 (6ABTO) was obtained using a high entropy design concept. The material, which has orthorhombic symmetry in space group A21am at room temperature, has Ca2+, Sr2+, Ba2+, Pb2+, Nd3+ and Na+...
