Title

Facile One-pot Synthesis of Iron Arsenide Nanoparticles: Toward Sacrificial Templates for [111] Superconducting Nanostructures

Abstract

Recently iron pnictide based compounds have been under immense scrutiny owing to discovery of superconductivity in the doped LnFeAsO (1111) and the AFeAs (A = alkali metal) series. the iron pnictide layer is believed to be responsible for superconductivity in these compounds. the sacrificial template method can be possibly used to synthesize nanostructured morphologies of these superconductors, where, one of the reactants, the binary iron pnictide will be used as a morphology directing agent. We have developed a one-pot soft chemical method to synthesize monodisperse iron arsenide nanoparticles. This is the first example of iron arsenide nanostructures in the literature. These FeAs nanoparticles are phase pure as revealed by powder x-ray diffraction and magnetic. Further, attempts are being made to introduce alkali metal ions in the solution to form nanostructures of the ternary [111] superconducting phase. Results encompassing synthesis of FeAs nanoparticles, nanowires and [111] nanostructures will be presented.
