Particle-hole symmetry reveals failed superconductivity in

At a low magnetic field, we observe a narrow superconducting phase, characterized by ρ xx that decreases exponentially with decreasing temperature and zero Hall effect. Upon increasing the magnetic field, the resistance of the sample starts to show saturation in the limit of T → 0, whereas the Hall effect does not seem to change from zero

The HTS magnet consists of 11 double-pancakes and provides stable 3.57 T operation at 37 K with a current of 120 A. Magnetic field shape, which is extremely important in gyrotron applications, was a considerable challenge since NbTi operating at 4.2 K is capable of a much higher current density than BSCCO operating at 37 K.

Why do MRI scanners use superconducting magnets rather

Broadly speaking, permanent magnets need to have their own innate magnetism, while superconducting magnets need to be able to hold large amounts of current when superconducting at low temperatures (the current creates the magnetic field).
