Paramagnon dispersion and damping in doped Na $_{x}$ Ca $_{2 - x}$ CuO $_{2}$ Cl $_{2}$

Blair W. Lebert, Benjamin Bacq-Labreuil, Mark P. M. Dean +13

Using Resonant Inelastic X-ray Scattering, we measure the paramagnon dispersion and damping of undoped, antiferromagnetic Ca $_{2}$ CuO $_{2}$ Cl $_{2}$ as well as doped, superconducting Na$_…

Giant Negative Thermal Expansion Induced by the Synergistic Effects of Ferroelectrostriction and Spin-Crossover in PbTiO3-Based Perovskites

Zhao Pan, Jun Chen, Runze Yu +18

The discovery of unusual negative thermal expansion (NTE) provides the opportunity to control the common but much desired property of thermal expansion, which is valuable not only…
