Diverse structures of mixed-metal oxides containing rare earths and their magnetic properties [in Japanese]
Access this Article
The solid state chemistry of mixed-metal oxides containing rare earths (4<i>f</i> elements) and 4<i>d</i> or 5<i>d</i> transition elements has attracted a great deal of interest, because these materials adopt a diverse range of structures and show a wide range of electronic properties due to 4<i>f</i> and 4<i>d</i> (or 5<i>d</i>) electrons. We have focused our attention on the structural chemistry and magnetic properties of perovskite-type oxides with the general formula A<sub>n</sub>LnM<sub>n−1</sub>O<sub>3n</sub> (A = Ca, Sr, Ba; Ln = rare earths; M = Ru, Ir; n = 1–4). Their structures are controlled by changing the ratio of the Ln and M ions, and peculiar magnetic properties and magnetic structures have been investigated by magnetic susceptibility, specific heat and neutron diffraction measurements.
