Supplementary dataset for "Magnetic recording fidelity of basalts through 3D nanotomography, 2024"

This repository contains raw data and scripts needed to reproduce the results presented in "Magnetic recording fidelity of basalts through 3D nanotomography, 2024". These include slice-and-view image stacks (VesuviusSnVTiffStack.tif for the Vesuvius dataset and HeklaSnVTiffStack.tif for the Hekla Volume) for the samples discussed in the manuscript. These were used to generate 3D meshes of magnetite grains in the volume using the methodology described in the manuscript. Individual Meshes Vesuvius.7z and Individual Meshes Hekla.7z contain the individual 3D mesh .pat files, while Hekla Full Volume.stl and Vesuvius Full Volume.stl show full 3D representations of the studied volumes. The individual mesh files can be used as geometry inputs for micromagnetic simulations using the MERRILL suite . Example MERRILL scripts are also included, with LEM_StateMerrilScript.merrill showing an example of a script used to determine the local energy minimum (LEM) state of a magnetic grain and NEB_Merril_Script.merrill showing a script to determine the energy barriers between LEM states used in the calculation of relaxation times. Finally ".csv" files containing grain metrics are also included for both of the studied samples ( HeklaGrainMetrics.csv and VesuviusGrainMetrics.csv ). These contain information on the size of the individual particles, their morphology, the LEM states they support and the energy barries from the NEB calculation.
