Low-temperature mass production of superconducting MgB2 nanofibers from Mg(BH4)2 decomposition and recombination.

ABSTRACT

Massive superconducting MgB(2) nanofibers are obtained for the first time from Mg(BH(4))(2). The technique optimizes reaction conditions to only 1 h at 460 °C and provides nanofibers which exhibited satisfying superconducting properties. The morphology transformation according to temperature changes and the special mechanism of precursor inductive synthesis are discussed.
