摘要：

Interest in the material Ca0.5Zn0.5Fe2O4 has been stimulated by the suggestion that it is superconducting up to 200 K. We have examined this material using a variety of experimental techniques and have concluded that this is not the case. Instead, it is a mixture of two phases, one of which, having the orthorhombic CaFe2O4 structure, undergoes a rather unusual transition at round 200 K whose physical properties and possible magnetic nature are discussed.
