• Magnetic properties of the perovskite-type oxide LaMnO_3 were studied in detail, experimentally and theoretically. The properly stoichiometric LaMnO_3 had a weak ferromagnetic moment in addition to the antiferromagnetic character with a Neel temperature of 141°K. It was found to be a parasitic weak ferromagnet. These results can be successfully explained using a phenomenological approach or the Spin-Hamiltonian formalism. The theoretical results show that the antiferromagnetic spin axis should be along the b-axis of the orthorhombic crystal axes and the ferromagnetic moment along the c-axis. The relation between a layer-type (A-type) antiferromagnetic superexchange interaction and the Jahn-Teller distortion of Mn^<3+> ions is also discussed.
