Magnetocaloric materials for cryogenic liquification

摘要

System and methods for cryogenic magnetocaloric refrigeration are provided. The system may include a magnetocaloric material including a single ion anisotropy and primary magnetic interactions of at most two dimensions. The system may also include a cryogenic fluid in communication with the magnetocaloric material, such that, when a magnetic field having a strength of at least a predetermined threshold is applied, the magnetocaloric material is configured to at least partially liquefy the cryogenic fluid.

1. A cryogenic magnetocaloric refrigeration system, comprising:
a cryogenic fluid; and a magnetocaloric material comprising a single ion anisotropy and magnetic interactions of at most two dimensions at the boiling temperature of the cryogenic fluid; wherein the cryogenic fluid is in communication with the magnetocaloric material, such that, when a magnetic field having a strength of at least a predetermined threshold is applied, the magnetocaloric material at least partially liquefies the cryogenic fluid; wherein the magnetocaloric material comprises LiFeBO3, LiMnBO3, LiCoBO3, or a combination thereof.
