Abstract:
The future of iron pnictide superconductors in technology is still undecided. While these materials are now known to
possess high critical temperatures and critical magnetic fields processing methods for these materials are still in their infancy. Recently we have been investigating possible ways to speed up the synthetic process for obtaining polycrystalline iron arsenide superconductors and other transition metal pnictides. Here we report the synthesis of NdFeAsO and NdFe₀.₉Co₀.₁AsO in less than one hour total exposure to microwave radiation using a secondary microwave susceptor to surround the reaction ampoule. Magnetic susceptibility and electronic resistivity measurements reveal the Co doped sample to be of high quality with a narrow transition range.
