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 ...

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 ...

To create this process, Cavalleri and colleagues applied ultrashort laser pulses to a thin, superconducting disc of yttrium barium copper oxide (YBCO), while also exposing the disc to an external ...
