Perhaps the most famous type of material used to create these objects is YBCO.
Perhaps the most famous type of material used to create these objects is YBCO. Current can jump a Josephson junction linking two of these objects. Based on the presence of a single or double critical magnetic field intensity, they are classified into Type I and Type II. Their formation is based on the condensation of Cooper pairs. They expel their magnetic fields in the Meissner effect, making them perfectly diamagnetic and thus allowing them to (*) levitate magnets. For 10 points, name these materials which have zero electrical resistance below a critical temperature.
