From the introduction: "Since the discovery of high
transition temperature (Tc) superconductivity in layered copper-based
oxides, extensive efforts have been devoted to the exploration of new
material systems containing transition metal ions other than copper in a
hope to realize higher transition temperatures because it is widely
believed that the high Tc values of the copper oxides are related to the
strong electron correlation associated with the transition metal ions.
Further, researchers have focused mostly on layered structures due to a
freedom to control the carrier density in the transition metal oxide layer.
These efforts have led to the discoveries of several novel
superconductors....Although their Tc's are much lower than those of the
copper oxides, the discoveries of
superconductivity in the new material systems provide valuable knowledge
for understanding physics underlying the oxide superconductors as well as
for finding an approach to a novel high Tc superconductor. Here we report a
new class of superconductor, an iron-based layered oxy-pnictide LaOFeP.
LaOFeP is composed of an alternate stack of lanthanum oxide and iron
pnictide layers...."
This 2006 report from the Journal of the American Chemical Society
was cited 26 times in current journal articles
indexed by Clarivate during July-August 2008. During that two-month
period, this was the third-most-cited chemistry paper published in the last
two years, aside from reviews. (Three of the same authors also account for
what is currently the #1 most-cited non-review paper in chemistry, a 2008
follow-up to the above report, also discussing iron-based
superconductivity: Y. Kamihara, et al., J. Am. Chem.
Soc., 130[11]: 3296-7, 2008.) Prior to the most recent bimonthly
