  • Abstract
    The structural, magnetic and electric properties of the Ba(Co1-xMnx)O3 oxides with x=0.00-0.25 were investigated. The samples with x=0.15,0.20, and 0.25 were found to be composed of the almost single phase of the 10H-type perovskite related crystal structure. The electric resistivity of the samples was significantly changed at around 50 K, and they had a dielectric characteristic below that temperature. In addition, the samples also showed the ferromagnetic behavior below. We will discuss the origin of the magnetism observed in the samples, in conjunction with the valence state of the transition metal ions.
