Title: Spin-charge-lattice coupling near the metal-insulator transition in Ca{sub 3}Ru{sub 2}O{sub 7}

Abstract

We report x-ray scattering studies of the c-axis lattice parameter in Ca{sub 3}Ru{sub 2}O{sub 7} as a function of temperature and magnetic field. These structural studies complement published transport and magnetization data, and therefore elucidate the spin-charge-lattice coupling near the metal-insulator transition. Strong anisotropy of the structural change for field applied along orthogonal in-plane directions is observed. Competition between a spin-polarized phase that does not couple to the lattice and an antiferromagnetic metallic phase that does gives rise to a rich behavior for B parallel b.
