Synth-Forc Loop Data.

This is an sqlite-lite binary file containing room temperature magnetic hysteresis loops and minor loops for a set of first order reversal curves (FORC)s. The data is generated using MERRILL (https://www.rockmag.org). It can be viewed using the command line sqlite (see https://www.sqlite.org). The file contains a single table, called 'all_loops' with the following fields:

id - a unique integer id for each row in the

geometry - a unique name of a geometry in this case 'oblate' and 'prolate' indicating an oblate truncated tetrahedron and a prolate truncated tetrahedron.

temperature - the temperature at which micromagnetic models were run in order to generate the data.

aspect_ratio - the aspect ratio of the geometries.

size - the size of each geometry - in nanometre, using a convention of equivalend spherical volume diameter.

Br - the reversal field of a minor loop.

B - the applied applied field.

M - the magnetisation that results from applying B (starting from Br).

volume - the volume of the grain (in nanometre cubed).

In order for the file to be consistent, it is recommended that each field step B is uniform across all geometries, sizes and aspect ratios.
