Patent number: 11728074Abstract: This invention relates to magnetocaloric materials comprising alloys useful for magnetic refrigeration applications. In some embodiments, the disclosed alloys may be Cerium, Neodymium, and/or Gadolinium based compositions that are fairly inexpensive, and in some cases exhibit only 2nd order magnetic phase transitions near their curie temperature, thus there are limited thermal and structural hysteresis losses. This makes these compositions attractive candidates for use in magnetic refrigeration applications. Surprisingly, the performance of the disclosed materials is similar or better to many of the known expensive rare-earth based magnetocaloric materials.Type: GrantFiled: February 20, 2019Date of Patent: August 15, 2023Assignees: General Engineering & Research, L.L.C., The Regents of the University of CaliforniaInventors: Robin Ihnfeldt, Eunjeong Kim, Sungho Jin, Renkun Chen, Xia Xu
