Marginal Fermi Liquid

Reviewing the situation of the experimental studies of the normal state in high-Tc super-conductors (HTS), we have put forward nine points to be necessarily considered in any theory of the normal state in HTS. It is argued that the two-dimension two-subsystem model is at least qualitatively consistent with all these nine points. On the basis of these arguments, the problem of the electronic pairing and variation in the normal state of metal has been discussed. We have put forward three variation of metals, i.e. the conventional metal (Fermi liquid), near conventional metal and the metal with the markedly pseudogapped metallic behaviour which may be a marginal Fermi liquid.

Ceramic Superconductors

We have fabricated superconducting composites composed of Y1Ba2Cu3O7–δ, copper oxide, and metallic silver. Sharp superconducting transitions were observed well above the liquid nitrogen temperature. The normal state resistivity of these composites was much lower than that of the pure ceramic Y1Ba2Cu3O7–δ. The critical current density was measured and it was comparable to that of ceramic superconductors. A substantial improvement of the mechanical properties has been achieved over those of the ceramic Y1Ba2Cu3O7–δ material.

Quantum Antiferromagnet

The normal state in-plane resistivity ρab and the out-of-plane resistivity ρc of high T c cupreous oxides are studied in terms of the interactions between the charged carries and the excitations including phonons in a doped quantum antiferromagnet which can be described by either a resonant valence bond (RVB) state or a quantum Néel state. We found that only in a properly doped quantum Néel state and when the renormalized the speed of spin wave becomes soft, ρab and σc = 1/ρc could have the desired experimental behaviors and depend linearly on T from T c up to room temperature if the quantum Néel state still, persists in high T c samples.
