New superconductors discovered in the Akimitsu laboratory are reviewed here. These materials can be categorized into two groups:
1) Cu-oxide superconductors.
1-1 Cu-oxide system having CuO2 planes.
1-2 Ladder lattice superconductor.
2) Exploration of new metal-based superconductors.
2-1 MgB2 and its application.
2-2 Y2C3.
2-3 Carrier-doped wide-gap semiconductors.
2-4 New superconductor with a cage-type structure: R5T6Sn18 (R = Sc, Y, Lu; T = Rh, Ir).
Finally, all of the new superconductors discovered in our laboratory are summarized. The outlook for the high-Tc superconductors and our present work are also described.
