Magnetic refrigeration based on the magnetocaloric effect is an energy-saving and environmentally friendly alternative to compression based cooling. The cooling effect is based on the heat release or uptake during a magnetic phase-transitions of a magnetocaloric material that can be controlled by a magnetic field. The decades-long search for an alloy suitable for mass application could be made much more efficient by digitizing the scientific process chain. The research project DiProMag thus seeks to digitize the entire research procedure from the production and characterization of magnetocaloric materials to their theoretical description and prototypical application. For this purpose, an ontology - that is a structured representation of knowledge - was developed using a hierarchical template-based approach for the acquisition, semantic representation and abstraction of raw ontological data. The focus of the project is on the advancement of Heusler alloys, with Co2CrAl serving as the first promising model system.
