Time resolved scanning Kerr microscopy (TRSKM) and time resolved soft x-ray measurement techniques will be used to study the sub-nanosecond dynamics of advanced materials that find application within magnetic recording technology. Of particular interest are the dynamics of spin-valve and tunnel-valve structures that are used to read information from magnetic hard disk drives, and the propagation of magnetic flux through tapered nanowires that may be used as the write pole in a recording head. The effects of spin transfer torque will be elucidated in lateral spin valve devices that provide direct access for optical and x-ray probes. The TRSKM measurements will be performed in Exeter while x-ray Ferromagnetic Resonance (XFMR) and time resolved x-ray photoemission electron microscopy (TRXPEEM) will be performed at the Diamond Light Source (DLS) and other leading synchrotron radiation sources. It is likely that the project will be partly funded by the DLS and there will be opportunity to make extended visits to DLS so as to make use of their outstanding experimental facilities.
