The first room-temperature ambient-pressure superconductor?
Guys, even if everything in this paper is true, the material as it is might have limited applications.<p>From what they show, the <i>critical field and critical current</i> seem very low. 2500 Oe is like 0.25 Tesla. Even REBCO at 77K is >1T. And 2500 Oe is not even at critical temperature but much lower. From skimming through the article I couldn't find the sample size of the current measurement to get the critical <i>current density</i>, not just current which is meaningless (and around 300 mA).<p>This means you can't actually push big current through this thing (yet). You can't make a powerful magnet, and you can't make viable power lines, both applications that were the hallmark of "room temperature superconductor revolution".<p>Of course, maybe one or a few more tweak(s) of the material and boom, it will give high J_c and B_c. I really hope it does, it would be super cool!
