Magnetic refrigeration based on the magnetocaloric effect can contribute to energy-saving and environmentally friendly cooling - from private households to industrial use. The cooling effect is based on heat release or uptake during a magnetic phase-transformation of the materials that can be controlled by a magnetic field. This process could replace refrigeration by conventional compressors, which often depend on environmentally harmful refrigerants. DiProMag aims at realizing and digitizing the entire process chain from the production and characterization of magnetocaloric materials to their theoretical description and prototype construction. Two Model systems – the Heusler alloys Co2CrAl and (NiCo)MnAl – are investigated for their structural, electronic and magnetic properties with respect to potential applications for magnetic cooling. OTTR templates are used for the acquisition and semantic representation of the available knowledge in the development of an ontology, as OTTR enables abstraction and natural understanding as a means of communication with domain experts. Furthermore, the ontology and additional unstructured data will be used to train a vector space that is analyzed concerning analogies to gain new hypotheses and knowledge.
