CaFe4As3: a metallic iron arsenide with anisotropic magnetic and charge-transport properties

J Am Chem Soc. 2009 Apr 22;131(15):5405-7. doi: 10.1021/ja900534h.

Abstract

The iron arsenide CaFe(4)As(3) features a three-dimensional network derived from intergrown Fe(2)As(2) layers and Ca ions in channels. Complex magnetic interactions between Fe atoms give rise to unexpected transitions and novel direction-dependent magnetic behavior.
