Tiny Space Magnets: X-ray Microscopy and Nanopaleomagnetism of Meteoritic Metal
… olivine grain from the Semarkona chondrite. Lorentz microscopy, transmission X-ray microscopy, nanotomography and micromagnetic simulations were used to rigorously test the behaviour of Fe-nanoparticles. The final study in this thesis focusses on the IAB iron meteorites. These meteorites have …

Characterisation of focused ion beam nanostructures by transmission electron microscopy
… size from ~5nm to ~30nm. The Fresnel mode of Lorentz microscopy revealed that a reduction in the mean moment was also observed at these doses but no clear changes in coercivity or magnetisation reversal behaviour were observed until the systems were rendered non-magnetic. This occurred at …

Observation and characterisation of magnetisation ripple using Lorentz transmission electron microscopy
Lorentz transmission electron microscopy (LTEM) has proved itself to be an invaluable technique when investigating in-situ micromagnetic behaviour of magnetic thin films. The nano-scale visualisation of the magnetic structure allows for not only the mapping of hysteresis behaviour, but quantitative …
