Trends High-temperature superconductivity in the iron pnictides

Abstract

In January of this year, a preprint appeared from the group of Hideo Hosono in Japan showing the existence of superconductivity in a layered iron arsenide material with a transition temperature (Tc) of 26 K [1]. The paper grew out of an earlier study that found a Tc of 5 K in the phosphide analogue [2]. In some ways the story looked very similar to what had… (More)
