Oxypnictide

Class of materials containing oxygen and a group-V element

In chemistry, oxypnictides are a class of materials composed of oxygen, a pnictogen and one or more other elements. Although this group of compounds has been recognized since 1995, interest in these compounds increased dramatically after the publication of the superconducting properties of LaOFeP and LaOFeAs which were discovered in 2006 and 2008. In these experiments the oxide was partly replaced by fluoride.
