Abstract

Our recent works on the search for new superconductors using soft-chemical techniques are reviewed. We have found new Mg-intercalated superconductors of MgxZrNCl and MgxHfNCl with Tc ∼ 13 K and 25 K, respectively. Moreover, we have succeeded in preparing bulk samples of hole-doped (La,Ca)2CuO4 with the Nd2CuO 4-type, namely, the so-called T'-type structure by reduction of (La,Ca)2CuO4 with the K2NiF4-type, namely, the so-called T-type structure using CaH2 at a temperature as low as 300°C and subsequent oxidation. This result is in contrast with the synthesis of (La,Ca)2CuO4 with the K2NiF 4-type structure by the conventional solid-state reaction method at a temperature as high as ∼1000°C.
