Hot Paper in Physics

"Supconductivity at 55K in iron-based F-doped layered quaternary compound Sm[O1-xFx]FeAs," by Zhi-An Ren and 10 others, Chinese Physics Letters, 25(6): 2215-6, June 2008.

Abstract: "We report the superconductivity in iron-based oxyarsenide Sm[O1-xFx]FeAs, with the onset resistivity transition temperature at 55.0 K and Meissner transition at 54.6 K. This compound has the same crystal structure as LaOFeAs with shrunk crystal lattices, and becomes the superconductor with the highest critical temperature among all materials besides copper oxides up to now."

This 2008 report from Chinese Physics Letters was cited 56 times in current journal articles indexed by Clarivate Analytics during March-April 2009. Only two other physics papers published in the last two years, aside from reviews, garnered higher citation totals during that two-month period. This is just one of several Top Ten papers, on the physics list as well as the chemistry list, that discuss iron-based superconductivity. Prior to the most recent bimonthly count, citations to the paper have accrued as follows:

January-February 2009: 37 citations
November-December 2008: 45
September-October 2008: 36
July-August 2008: 18
Total citations to date: 192
