What is it about?
By utilizing magnetocaloric effect (entropy change) of antiferromagnetic to ferromagnetic transition at low temperature, an efficient cooling technology down to cryogenic temperature (around 150 K or -120 degree Celsius) is attained.

Why is it important?
Magnetic cooling temperature range is tunable by adjusting the materials’ composition with different magnetic transition point. The cooling down to 20 K finds potential application for liquefied hydrogen storage that can contribute to green energy technology. Mn3GaC shows a metallic anti-perovskite structure that is important as a mother phase of recently topical MAX phase (layered metallic carbides or nitrides) compounds.
