Research Abstract

In transition metal oxides with exotic valences, we can expect interesting magnetic and electric properties. In this study, we searched new materials using a hydrothermal method with which we can control redox condition in a closed system. As a result, we discovered six novel compounds. X-ray structural analyses and measurements of magnetization revealed that most of them have characteristics of a frustrated magnet in which a trivial magnetic order is suppressed because of a singular arrangement of the transition metal atoms.
