This doesn't look superconducting at all to me, simply the sample is very small and below 110K the resistance of the sample is too small to be measured by their measurement equipment. I'm happy to be proved wrong but there should be a steeper transition at the critical temperature.
- gus_massa 3y agoNote that the graphic is in log escale. Also, it looks like it's more complicated https://www.researchgate.net/figure/Superconducting-transition-curves-of-the-microstructures-on-different-substrates_fig3_232244484 https://www.researchgate.net/figure/Superconducting-transiti... Also, IIUC the method makes a lot of small grains with different composition, and they may become superconductors at different temperature, and make a dirtier curve. Also, not my research area, so I'm guessing a bit.
