Summary on Grant Application Form |
This proposal seeks funding to investigate the synthesis of new layered manganese oxides, which are currently of great interest for their anisotropic magnetic properties and potential magnetoresistive behaviour. In this highly competitive area, we propose to explore a new, two-stage approach for the synthesis of such materials, which may be likened to the rationale of molecular synthesis rather than traditional solid state chemistry. The first stage will exploit the coordination preferences of Mn2+/Mn3+ cations, to engineer new layered structures. Appropriate low temperature treatments, will subsequently be used to functionalise the magnetic and electronic properties. To inform our selection of target materials we intend to utilise many of the structural motifs discovered during the extensive studies on the cuprate superconductor materials, an area of chemistry in which we are particular experienced, and which is highly relevant owing to the similar Jahn-Teller coordination preferences of Cu2+ and Mn3+ ions. We believe our proposed synthetic methodology appears to offer enhanced potential for the synthesis of manganese analogues of cuprate phases. Full structural, electronic and magnetic characterisation of the synthesised phases will be performed to enable an improved understanding of the nature of magnetic interactions in these solids and its correlation to electrical properties. In turn, this provides the means of optimising properties and in particular magnetoresistive behaviour.
