Abstract

A novel solid-solution system between CaCu3Ti4O12 and CaCu3Ru4O12 was synthesized using high-pressure synthesis technique. In order to search an exotic phase in the system and clarify the microscopic magnetic nature in the x range between 0.5 and 2.5, we wish to use a microscopic magnetic tool, i.e. muons.
