Magnetic refrigeration based on the magnetocaloric effect is an environmentally friendly alternative to compression based cooling. The cooling effect is based on heat release or uptake during magnetic phase-transitions of a magnetocaloric material. The decades-long search for alloys suitable for mass application could be made much more efficient by digitizing the scientific process chain. The project DiProMag seeks to digitalize the process chain from theory, simulation and experiment to prototypical applications in an ontology. Here, we show how experimental results are implemented in a hierarchical ontology. Various Heusler alloys have been investigated as thin films, nanostructures, and bulk material. Different approaches have been developed for these materials to be integrated into functional prototypes. The goal is to standardize data evaluation and reporting to make it more accessible and comparable across different fields within the community.
