Creating a bipolarity of semiconductors has been a key technology to develop recent advanced semiconductor devices. Although theoretical calculation predicts the presence of ferromagnetic electron-doped manganites with doping tetravalent cations, the ferromagnetic origin in experiments has been controversial due to the lack of direct experimental evidence. Here, we investigate the ferromagnetism in (La,Ce)MnO thin films by measuring the magnetic circular dichroism in soft X-ray absorption (XMCD). The XMCD measurements clarified that the ferromagnetism is not caused by the presence of Mn
but by self-hole doping for manganese.
