Rare-earth barium copper oxide
Rare-earth barium copper oxide is a family of chemical compounds known for exhibiting high temperature superconductivity.
ReBCO superconductors have the potential to sustain stronger magnetic fields than other superconductor materials.
Due to their stronger magnetic field and relatively high superconducting critical temperature, these materials have been proposed for future magnetic confinement fusion reactors such as the ARC reactor, allowing a more compact and economical construction.
Any rare-earth element can be used in a ReBCO; popular choices include yttrium, lanthanum, samarium, neodymium, and gadolinium.
