| Abstract(in English) | The enrichment of library for antiferromagnetic material is essential for the development of magnetoresistance (MR) devices and magnetic devices with THz operation. Neutron diffraction, which has been usually used to evaluate the magnetic structure of bulk antiferromagnets, is difficult to be applied to thin films. In this study, we investigated the magnetic structure of antiferromagnetic thin films via the current and magnetic field orientation dependence of the MR effect in C11b Cr2Al (001) thin films. As results, we confirmed the existence of the anomalous MR effect originating from the magnetic moment of Cr and inferred that the magnetic moment lies in the c-plane from the rotational symmetry. Further investigation is needed to determine the magnetic ordering in the c-plane. |
