- Abstract:
- Accurate recordings of the ancient magnetic field are primarily thought to be due to grains which are small and uniformly magnetised. The magnetisation in these single-domain grains becomes 'frozen' in the ambient field direction as the rock cools. However, natural samples often contain larger grains which are multi-domained. The recording of the magnetic signal by these grains is thought to be very 'soft' and unreliable, and should be easily removed by a weak alternating magnetic field or mild heating. However, there is increasing evidence that this is not so. This project will combine advances in micromagnetic modelling with novel experimental studies on laboratory and natural samples in order to understand the mechanism of multidomain magnetic recording.
