Magnetic and charge order of the cobalt oxide La{2-x}Ba{x}CoO{4}
We propose an experiment to investigate the magnetic and charge order of the layered cobalt oxide La{2-x}Ba{x}CoO{4} for two different hole-doping concentrations x = 1/2 and x = 1/3. To our knowledge, this compound has not yet been studied by neutron scattering. It is structurally similar to high temperature superconducting cuprates. The mechanism and phase transitions leading to superconductivity in the cuprates are not well understood but do involve competition between the ordering of magnetic moments and charges. Here we intend to study this competition in La{2-x}Ba{x}CoO{4}: a material that shares an insulating parent phase with the cuprates, but does not become superconducting. Data obtained on D10 from superstructure reflections will allow us to compare the material to previously measured cobalt oxides such as La{2-x}Sr{x}CoO{4}, and develop an improved account of spin wave excitations in complex condensed matter systems.
