Latest Patents

Caldwell holds a patent for "Magnetocaloric alloys useful for magnetic refrigeration applications." This invention relates to magnetocaloric materials comprising ternary alloys that are particularly useful for magnetic refrigeration. The disclosed ternary alloys are based on Cerium, Neodymium, and/or Gadolinium compositions, which are relatively inexpensive. These materials exhibit only second-order magnetic phase transitions near their Curie temperature, resulting in minimal thermal and structural hysteresis losses. This characteristic makes them attractive candidates for magnetic refrigeration applications. The performance of these materials is comparable to, or even better than, many known expensive rare-earth-based magnetocaloric materials.
