Are Complex Oxides "Simple"?
Date: Friday September 13, 2013
Time: 12:00 pm – 1:00 pm
Location: Houston Science Center – Building 593 — Room 102
Overview
We will present synthesis strategies to access model compounds for the study of certain structure-property relationships. A rare class of complex oxides are Na5[MO2][X] because they can be regarded as coordinative "unsaturated". However, they adopt a simple structure type of an anti-perovskite. [1] Likewise, we have intensified our search for specific series of compounds that can be used as templates to study frustration effects in triangular antiferromagnets. Here, interesting aspects arise from the study of charge and pressure effects on the magnetic properties. [2-4] Also, upon doping with non-magnetic ions one can achieve the ordered formation of a honeycomb lattice. Recent examples for one-dimensional magnetic properties are complex oxide-halide intergrowths compounds. In summary, we will discuss selected examples for "simple" oxides with respect to their structures and physical properties. Furthermore, lattice dynamic studies by Raman spectroscopy and DFT methods, magnetic and specific heat measurements, as well as magnetic structures derived from neutron diffraction experiments will be presented.
