The are also brittle, and as an added bonus they tend not to be chemically stable in humid air. However, their very existence showed that high temperature superconductivity is actually far more generic than first appeared, and as you say they provide additional ways of testing different mechanisms for pairing. If the 100k result turns out to be right, that would undoubtedly spur much more research into the engineering of these materials and their interfaces for possible applications.Douglas Natelsonhttps://www.blogger.com/profile/13340091255404229559noreply@blogger.comtag:blogger.com,1999:blog-13869903.post-13058560289495827162014-06-19T22:37:19.191-05:002014-06-19T22:37:19.191-05:00I know that iron based superconductors have gotten...I know that iron based superconductors have gotten a lot of attention and generated a lot of excitement in the condensed matter community. From a technological/engineering perspective, what are some advances that these iron based superconductors offer over copper oxide based superconductors? Are these iron based superconductors more malleable for example? Is there any engineering advantage or is the excitement related to how these new class of materials can help achieve a better understanding of high-Tc superconductors (which is very important as well)?Anonymousnoreply@blogger.com
