Outline of Final Research Achievements

Recently, hydride-doping effect in oxide and oxyhydride have been investigated in strongly-correlated system. In this study, we construct dielectric measurement system, and research calcium niobium nickel oxide. The oxide show multiferroic feature at 5 K from results of physical properties (magnetic and dielectric properties). And it is derived from the 120-degrees spin structure from the results of powder neutron scattering.
Furthermore, we tried hydride-doping by using hydrogen source. The compound after synthesis has different color, and little shift of magnetic transition.
