The dataset contains measurements of magnetic susceptibility in dependence of temperature of shocked magnetite and of a natural magnetite single crystal before and after manual crushing. A python code for evaluation of low-temperature susceptibility curves is included. The data are supplementary to: Fuchs, H., Kontny, A. and Schilling, F.R., 2024. Stress-induced Changes in Magnetite: Insights from a Numerical Analysis of the Verwey Transition, Geophysical Journal International ... : The data set contains k-T curves of - Initial magnetite ore from Sydvaranger mine (Norway) - the same ore after shock at 3, 5, 10, 20 and 30 GPa under laboratory conditions and after subsequent heating to 973 K -Natural magnetite single crystal (initial and after manual crushing) The data set contains a python code for evaluation of normalized low-temperature k-T curves. Experimental conditions are described in [1]. The approach for k-T curve evaluation is described in [2] [1]: Kontny, A., Reznik, B., Boubnov, A., Göttlicher, J. and Steininger, R., 2018.
