Abstract:
Micromagnetic Tomography is a new technique which combines magnetic surface scan of a sample with spatial information (shape, location) of magnetic grains. Combining these two datasets enables us to overcome the non-uniqueness in the inversion and thus we can allocate magnetizations to individual grains that best reproduce the magnetic surface scan. This is a step into understanding how magnetic fields are recorded in magnetic grains, which is relevant for the field of paleomagnetism.

Comment:
The data in this repository consists of three parts; (1) the magnetic surface scan, (2) the spatial data and (3) the raw dataset. The orientation and scale of file 1 matches the orientation and scale of file 2. This means that using file 1 and 2, an inversion for the magnetic grains can be performed. If the exact same procedure is used as described in the manuscript this dataset is supplement to, then the magnetizations from file 3 can be reproduced. The magnetizations in file 3 can also be filtered and interpreted to reproduce various figures from the manuscript.
