Pnictide

"Our results provide further evidence that the undoped iron pnictide parent compounds are on the verge of Mott localization," Abrahams said. ❋ Unknown (2010)

"Unfortunately, there is no pnictide material with those properties." ❋ Unknown (2010)

In work published earlier this year, Si and colleagues replaced arsenic atoms in one of the intervening layers of a pnictide with slightly smaller phosphorous atoms. ❋ Unknown (2010)

By scanning an iron-pnictide superconductor with a probe that measures the depth that a magnetic field penetrates the material, the researchers could determine the regions where superconducting currents are strongest. ❋ Unknown (2010)

More specifically, while the electrons in the cuprates are strongly correlated -- meaning the energy of one electron is tied to the energy of the others -- the electrons in the iron-pnictide superconductors behave more like those of a normal metal in which the electrons do not (to first approximation) interact. ❋ Unknown (2009)

The timing of the testing phase for ARCS was ideal because in the preceding months, a new class of superconducting materials - pnictide compounds based on iron and arsenic - was discovered. ❋ Unknown (2008)
