Room-temperature ferroelectricity in A-site ordered Ruddlesden-Popper Li2CaTa2O7 ceramics
In the present work, the crystal structure, ferroelectric and dielectric properties of the dense single-phase Li2CaTa2O7 ceramics with A-site ordered double-layer Ruddlesden-Popper structures have been investigated by the experiments and first-principles calculations. A polar Pna21 phase was determi...
