We have synthesized the samples of LuFeO, which shows the ferroelectricity due to charge ordering of Fe ions, under several different reducing conditions using a CO-CO flow. The reducing condition was changed by changing a flow ratio of CO and CO. It was found that the flow ratio of CO/CO of about 5 provided the sample with the highest magnetic transition temperature of 240-250 K. This sample showed the dielectric constant of 10000 at room temperature. The imaginary part of the dielectric response offered the activation energy of 0.4-0.5 eV, which is slightly larger than that reported previously (about 0.3 eV). We will perform further investigation of the physical properties of this sample to clarify full details and their origin of LuFeO.
