Онлайн-гонка за комнатной сверхпроводимостью

сверхпроводник до 110К

Нет такого утверждения.

А какой критерий сверхпроводимости? Сделать кольцо и навести в нём ток?

«Fig. 3(a) shows the temperature dependence of resistance sample S1, with a clear zero resistance characteristic observed at 110 K, indicating the possibility of superconductivity. It is worth noting that some other pieces exhibit semiconductor behavior, consistent with the literature [22].»

«When the magnetic field is increased to more than 7 T, the resistance trend is abnormal, which is contrary to normal superconductors that the external magnetic field will simply reduce the critical temperature of superconductivity. The specific reason needs our further study. More importantly, the zero resistance is robust under magnetic field, which indicates possible large upper critical field in this material. To further verify the superconducting properties, we conducted magnetic measurements on the sample, but unfortunately, no obvious Meissner signal was observed, indicating that the superconducting volume fraction of the sample may be very small.»

Значительно более понятная работа чем то, что опубликовали первопроходцы.
