I've recently become fascinated with a cryo cooling method known as "magnetic refrigeration". Here is the Wikipedia article. I was wondering if there is a list of magnetocaloric materials.
Specifically, I was wondering if the chemical compound Yittrium Barium Copper Oxide (YBCO), a high-temperature superconductor, is in this list. It would be wonderful to refrigerate this superconductor with magnetism rather than with (disposable) liquid nitrogen. Whereas the liquid nitrogen would be used up, a magnetic refrigeration setup only consumes electricity and is a more permanent solution to refrigerating the superconductor.
