Research in the group is primarily based on thin film magnetic properties, which include research into spin electronics and the magnetic properties of perovskites. The molecular beam epitaxy system contains three electron beam sources that can allow the evapapouration of up to seven different materials, with facilities for sample rotation, tilting, heating, ion bombardment, RHEED, Auger electron spectroscopy, the Magneto-Optic Kerr Effect (MOKE) and, by transfer under vacuum, UHV Scanning Tunelling Microscopy. Facilities also exist for lithography and patterning of the films into nano-structures. In-house ex-situ characterisation is by VSM, MOKE, XRD (X-ray Diffraction), magnetotransport, the MagnetoRefractive Effect (MRE), FerroMagnetic Resonance (FMR) and torque magnetometry. Further characterization of samples is performed at both UK and European central facilities. Element specific structural and magnetic characterisation is conducted at Daresbury laboratory using Medium Energy Scattering (MEIS) and Magnetic X-ray Circular Dichroism (MCXD). X-ray scattering measurements are performed at the SRS-Daresbury and at the ESRF-Grenoble synchrotrons. Finally, neutron scattering experiments are performed at the ILL reactor.
