Abstract
In this study, we successfully synthesized a novel A-site columnar-ordered perovskite CaZnV2O6. This compound features a square-planar-coordinated Zn2+disorder, which is the same characteristic as the centrosymmetric paraelectric CaMnTi2O6. Unlike CaMnTi2O6, which shows a centrosymmetric paraelectric–noncentrosymmetric ferroelectric transition, CaZnV2O6retains Pauli-paramagnetic metallicity arising from itinerant V4+d1electrons and centrosymmetry down to 5 K. Based on analogous compounds, we expect CaZnV2O6to provide a new playground for the electronic and magnetic states of V4+.
