RE: Another new use for Vanadium :-)19 Jun 2018 08:59
Gambit - this of course is quite precisely my field - the interplay between superconductivity and magnetism. In fact it was some of our experiments in Cambridge in the mid 90's on a field of materials called Heavy Fermions which paved the way for this generation of research. Rutgers did not have an experimental low temperature group to speak of at that time, but they did have theoretician Piers Coleman, also ex Cambridge, and brother of Killing Joke's Jaz Coleman, but that's a whole other story.
Anyways the bottom line is that the idea that superconductivity and magnetism are somehow mutually incompatible was shown experimentally back then to be only true for classical phonon-mediated superconductivity - that's an old headline. What is interesting is the way that soft magnetic fluctuations can participate in more novel forms of superconductivity such as that mentioned in the article. I've been out of the game for about 10 years now so have now kept up with every single research paper but this is the first time I've seen Vanadium based compounds used in these types of experiments.
Don't hold your breath for large applications of this research, usually the superconductivity happens at temperature 1/100 th that of room temperature and the samples under study can be below 1mg in weight (one of mine in a high pressure apparatus was so small as to only just be visible to the naked eye.)
