A window on the early solar system: Magnetic nanostructures in meteorites

Meteorites can tell us a great deal about the magnetic state of the early solar system, and may even shed light on how Earth's own magnetic field is generated. This talk reveals how the nanoscience of magnetic meteorites is being used to decode magnetic signals frozen into these ancient materials.

Dr Richard Harrison, Reader in Earth Materials Science, employs a combination of state-of-the-art experimental techniques, including transmission microscopy, electron holography, neutron and X-ray scattering, together with atomistic and micromagnetic modelling, to study the fundamental properties of magnetic minerals at the nanometre scale.
