Summary on Grant Application Form |
|
By tuning to elemental absorpion edges huge increases in X-ray scattering can be obtained. We have been the first to extend X-ray diffraction from single crystals into the soft X-ray regime allowing us to acess the L-edges of the 3d transition metals. We have shown that this can be used to obtain new information on charge, spin and orbital ordering in transition metal oxides. We have recently been awarded a long term access grant to use the world's best soft x-ray diffractometer at the National Synchrotron Light Source at Brookhaven National Laboratory, USA. This grant will provide travel and accomodation costs to enable us to undertake experiments during our alloted beam time. The diffractometer at X1 B has many advantages over any other facility worldwide. In particular in has a low tempeature facility allowing a base temperature of -25 K, this will anable us to undertake experiments ahich are currently impossible at any other facility.We propose to study ternary intermetallics such as HoFe4Al8 which display complex magnetic ordering at low temperatures as well as transition metal oxides such as manganites, cuprates and nickelates. Our studies will provide unique new information on these strongly correlated materials and the interplay between charge, spin and orbital degrees of freedom. These experiments cannot be conducted at any other facility worldwide such as SRS Daresbury or ESRF, Grenoble.
