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 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
