"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


SOURCE: Hot Papers Database (Included with a subscription to the print newsletter Science Watch®, available from the Research Services Group of Thomson Reuters. Packaged on a CD that is mailed with each Science Watch issue, the Hot Papers Database contains data on hundreds of highly cited papers published during the last two years. User interface permits searching by author, organization, journal, field, and more. Total citations, as well as citations accrued during successive bimonthly periods, can be assessed and graphed. An updated CD containing the most recent bimonthly data is mailed with every new issue of Science Watch, six times a year. The CD also includes an electronic version of the Science Watch issue in HTML format, for personal desktop access.
