Abstract
A cold storage material and a preparation method therefor and an application thereof are provided. The cold storage material includes a Gd2O2Se crystal, which undergoes a phase transition near 6.22 K and exhibits high specific heat in 1-10 K temperature range with pronounced magnetocaloric effects, making it suitable as a cold storage material at liquid helium temperatures.
Claims9
A cold storage material comprising:
- a Gd2O2Se crystal.
A cold storage device, comprising:
- a cold storage cylinder,
- a first partition member,
- a second partition member, and
- a third partition member arranged at intervals within the cold storage cylinder,
- wherein the first partition member, the second partition member, and the third partition member are configured to permit gas flow in a direction from the first partition member toward the third partition member;
- the first partition member, the second partition member, and the cold storage cylinder form a first accommodation space;
- and the second partition member, the third partition member, and the cold storage cylinder form a second accommodation space;
- and
- the first accommodation space is filled with a front-stage cold storage material and a mid-stage cold storage material;
- and the second accommodation space is filled with a rear-stage cold storage material.
