Abstract: Perovskite potassium sodium niobates, K1−xNaxNbO3, are promising lead-free piezoelectrics. Their dielectric and piezoelectric characteristics peak near x = 0.5, but the reasons for such property enhancement remain unclear. We addressed this uncertainty by analyzing changes in the… read more here.

DOI: 10.1103/physrevb.101.085101
Abstract: Layered perovskite iridate ${\mathrm{Sr}}_{2}{\mathrm{IrO}}_{4}$ shares many similarities with high ${T}_{\text{c}}$ cuprates and is expected to host novel superconductivity but has never been realized experimentally. Despite the similarities, the prominent ${\mathrm{IrO}}_{6}$ octahedral rotations and sizable net… read more here.
