Structure and Ferromagnetism in Mn4+ Spinels: AM0.5Mn1.5O4 (A = Li, Cu; M = Ni, Mg)
Source abstract
Abstract
The structure and electronic properties of a series of Mn IV spinel oxides, with the general formula, AM 0.5 Mn 1.5 O 4 (A = Li, Cu; M = Ni, Mg), are investigated. These materials form an interesting analogy to pyrochlore structures that show colossal magnetoresistance properties. Studies of all the compounds show spontaneous magnetization at a well-defined transition temperature and their semiconducting nature.
