Summary on Grant Application Form |

The project will provide basic support for applications of x-ray dichroism by magnetism groups in Birbeck, Cambridge, Coventry, Daresbury, Leicester, Salford, Sheffield and York. These measurements will give information on element and site specific moments, element specific hysteresis, ratios, magnetostriction and the magnetic characterisation of nanostructures. There will be a strong emphasis on magnetocrystalline anisotropy with exploitation of x-ray dichroism measurements in the transverse geometry, a technique recently developed in the Daresbury laboratory. The anisotropy programme will include samples from York (thin film Co, CoPt alloys and trilayers, CoAg heterogeneous alloys), Daresbury/Grenoble (FePd, CoPd and FeCoPd thin film alloys), Cambridge (Co/Ni/Co multilayers), Coventry (heterogeneous alloys) and Salford (Fe/Au, Fe/Ag multilayers). A new electromagnet facility will allow hysteresis measurements on many systems to be measured quickly and routinely, while the introduction of fluorescence detection both increases sampling depth so that a wide range of systems can be investigated and reduces the field sensitivity of the detection in an applied field. Finally, the project will attempt to publicise the potential of dichroism to a wider magnetism community and encourage wider use of the technique in magnetic systems of direct industrial relevance.
