Summary on Grant Application Form
MFM in association with AFM will be used to obtain key magnetic microstructural information. Micromagnetic modelling will be undertaken on model magnetic materials in order to understand the relationship between tip/sample spacing, tip field characteristics and the image. The work sequence will allow experience to be gained on model materials progressing towards examination of more complex structures. The domain structure will be examined in 3-D transition metal based amorphous ribbons in order to investigate the extent of ideal ferro-magnetic alignment and to correlate these features with the moment correlation lengths. MFM will be conducted on nano- and micro-phase rapidly solidified hard and soft magnetic alloys to establish the domain structure as a function of composition, grain size, grain shape and magnetisation. Combined MFM/AFM will be used to study the perfection of laser ablated thin films and magnetic multilayers and to correlate magnetic domain structure as a function of surface topography, film thickness and film protection. Particular emphasis is placed on the characterisation of the sensing tip and the use of a range of tip types and reversed tip polarity in order to obtain high resolution results, to separate magnetic from topographical and van der Waals information and to allow the study of soft magnetic materials with low coercivities.
