【 摘 要 】

We successfully synthesized polycrystalline samples of new layered compounds Ae2ScO3CoP (Ae = Sr, Ba) and Ba2ScO3CoAs, members with CoPn conduction layers, and measured magnetizations of them. As results, magnetic parameters, i.e. the Curie temperature and the Weiss temperature, are found not to be correlative with lattice parameters a nor c in the case of Ae2ScO3CoPn compounds, including Sr2ScO3CoAs, unlike the case of three dimensional itinerant electronic ferromagnets. We suggested that structural parameters of CoPn4tetrahedron are good parameters to relate to magnetic parameters in the case of compounds with CoPn layers.
