The typical multi-layer cuprate superconductor
What is there?
Challenge toward higher performance,
higher Tc, higher Jc,
higher Hirr, lower anisotropy,
advanced synthesis methods of bulk, single crystal and films.
The multiple order parameters and its dynamics are studied.
Two Tc of Cu-1234 and coexistence of anti-ferromagnetic order and superconductivity in Hg-1245
are brand-new concepts.
Fruits of the project
The discovery of Tc > 134 K on Tl-1223 (TlCu1223) superconductor.
(Tc is comparable to that of Hg-1223 having the highest Tc)
TlCu-1223 films for microwave application. (For > 90 K operation)
The filter for IMT2000 will be appeared until end of 2003.
The fundamental study on the multi-layer cuprate superconductor leads discover of i-soliton,
the basic concept of the third generation Josephson computer.
Beyond the project
Our final goal is the development of room temperature superconductors.
