  • IRON-RHODIUM MAGNETOCALORIC ALLOY RIBBONS FOR HIGH PERFORMANCE COOLING-HEATING APPLICATIONS AND PROCESS FOR MANUFACTURING THE SAME
    Publication number: 20220084728
    Abstract: A polycrystalline magnetocaloric material based on thermally annealed Fe100-xRhx melt-spun ribbons with chemical composition x in the interval 48?x?52 at. % and the bcc CsCl-type crystal structure (B2) and method for manufacturing the same. The material has improved magnetocaloric properties associated to first-order magneto-elastic phase transition compared to bulk alloys of similar chemical composition manufactured by conventional melting techniques; exhibiting both low-magnetic field induced giant magnetocaloric effects and enhanced refrigeration capacity close to the room temperature range, due to the fast increase of a magnetic entropy change at low fields that is followed by a broad table-like magnetic entropy change as function in the temperature curve.

  • Magnetocaloric material based on NdPrFewith improved properties
    Patent number: 9941037
    Abstract: The instant invention relates to a magnetocaloric material based on NdPrFe17 melt-spun ribbons. This material has improved properties when compared with other similar magnetocaloric (MC) materials since it has an enhanced refrigeration capacity in the room temperature range due to its broader magnetic entropy change as function of the temperature curve. This material is useful as magnetic refrigerant as a part of magnetocaloric refrigerators.
