In the early superconductors, including all of the elemental superconductors except niobium, the superconductivity is quenched in relatively low magnetic fields. In contrast, type II superconductors have two critical fields. The first is a low-intensity field H c1, which partially suppresses the superconductivity.

Discovery of Sodium-Doped Triphenylene Superconductors …

Fig.4 shows SEM images of powder samples of A60. The image of A60 indicates an average particle size much less than 1µm, but some thin fibres between the particles are shown in same image. In addition, EDX analysis indicated four different phases are formed in sample A60 during the grinding process. These phases are Y-rich, Cu-
