The superconductor in question here is a mix of yttrium, barium, and copper oxide that goes by the merciful acronym YBCO. The easy way to make YBCO involves multiple rounds of pulverizing yttrium ...

Instead, researchers use it to form compounds, such as yttrium barium copper oxide (YBCO) — which helped usher in a new phase of high-temperature superconductivity research. Yttrium is also ...

Twenty years ago this spring, they discovered that a crystalline compound of lanthanum, barium, copper and oxygen becomes ... would be enhanced in related oxide materials with strong Jahn ...

“From a magnetic point of view, this device acts like a wormhole, as if the magnetic field was transferred through an extra special dimension,” lead ... of yttrium barium copper oxide (a ...

Type II superconductors are more complex materials, typically alloys or compounds, such as niobium-tin (Nb3Sn) and yttrium barium copper oxide (YBCO). They have two critical magnetic fields: a lower ...
