Summary on Grant Application Form |
|
There is presently no facility in the UK which can be used by the academic and industrial research community, capable of imaging and analysing the magnetic behaviour of a wide range of materials and devices at very high frequencies with a minimum of sample preparation. This is a particular drawback to developments in information storage, but has much wider implications throughout the Advanced Magnetics Programme. It is intended to construct a facility, based around a confocal scanning laser microscope, which will remedy this situation and provide a comprehensive dynamic test environment for the magnetics community. A combination of pulsed and c.w. lasers will be used to illuminate either full-field or in a diffraction-limited scanned spot. Full-field imaging in low light/low contrast will be undertaken by a cooled ccd camera and diffraction-limited scanned imaging by multiple photodiodes with sub-ns response speed. For vector analysis of planar magnetisations with very weak signals a network/spectrum analyser with dc to 500MHz bandwidth will give adequate signal recovery for imaging. Confocal, short wavelength imaging with high NA lenses should enable 250nm resolution.
