Patrick Woodward

About

Patrick Woodward is the Newman Professor in the Department of Chemistry and Biochemistry at The Ohio State University. He received B.S. degrees in Chemistry and Engineering from Idaho State University in 1991, followed by a M.S. in Materials Science and a Ph.D. in Chemistry from Oregon State University in 1996, where he studied solid state chemistry with Art Sleight. His postdoctoral work was conducted in the Physics Department at the National Synchrotron Light Source, focusing on advanced x-ray and neutron powder diffraction techniques under the supervision of Dave Cox. He joined Ohio State University as an assistant professor in 1998, was awarded a CAREER Award from the National Science Foundation in 2001, and was promoted to Associate Professor in 2004. His research centers on solid state chemistry, aiming to understand the correlation between composition, crystal structure, and physical properties to facilitate the rational design of new materials. His work includes the study and design of semiconducting oxides and oxynitrides, coupled electronic and magnetic properties of transition metal oxides, and the development of new dielectric materials, utilizing diffraction techniques such as Rietveld refinements, ab-initio structure solutions, and synchrotron and neutron diffraction.

  articleSenior authorCorresponding

  Here, we present the synthesis and crystal structure of Rb3InCl6 prepared from air stable reagents via a two-step process that proceeds through the intermediate Rb2InCl5·H2O. Rb3InCl6 crystallizes with the Rb3YCl6 structure type (C2/c), which can be derived from the double perovskite structure by noncooperative tilting of isolated [InCl6]3– octahedra. Despite this lowering of symmetry, the optical properties are similar to the cubic double perovskite Cs2NaInCl6. Partial substitution of In3+ with…

• Cs₄Cd_1–<i>x</i>Mn_<i>x</i>Bi₂Cl₁₂—A Vacancy-Ordered Halide Perovskite Phosphor with High-Efficiency Orange-Red Emission

  Chemistry of Materials · 2020-03-25 · 92 citations

  articleSenior authorCorresponding

  The structural, optical, and magnetic properties of the vacancy-ordered quadruple perovskites Cs4CdBi2Cl12 and Cs4MnBi2Cl12 and their solid solution have been investigated. Both compounds crystallize with the R3̅m space group symmetry that arises from the ordering of Bi3+, Mn2+/Cd2+, and cation vacancies into layers that run perpendicular to the ⟨111⟩ direction of the cubic perovskite structure. Cs4MnBi2Cl12 is paramagnetic down to 2 K with a Weiss constant of −2.88(3) K and an effective moment…

• Origin of Magnetism in a Supposedly Nonmagnetic Osmium Oxide

  Physical Review Letters · 2024-08-05 · 18 citations

  articleOpen access

  A supposedly nonmagnetic 5d^{1} double perovskite oxide is investigated by a combination of spectroscopic and theoretical methods, namely, resonant inelastic x-ray scattering, x-ray absorption spectroscopy, magnetic circular dichroism, and multiplet ligand-field calculations. We found that the large spin-orbit coupling admixes the 5d t_{2g} and e_{g} orbitals, covalency raises the 5d population well above the nominal value, and the local symmetry is lower than O_{h}. The obtained electronic inte…

• Exploring the Links between Structural Distortions, Orbital Ordering, and Multipolar Magnetic Ordering in Double Perovskites Containing Re(VI) and Os(VII)

  Chemistry of Materials · 2024-11-28 · 6 citations

  articleOpen accessSenior authorCorresponding

  A combination of high-resolution powder diffraction techniques and solid-state NMR has been employed to explore the links between crystal structure, orbital ordering, and magnetism in three isostructural double perovskites containing transition metal ions with a 5d1 configuration. In Ba2ZnReO6, both neutron and synchrotron X-ray powder diffraction data reveal a cubic-to-tetragonal transition at 23 K that breaks the degeneracy of the t2g orbitals and leads to a pattern of orbital ordering that st…
