This is an invited tutorial review of high temperature superconductors for the IEEE Communications Society.

It has long been believed that superconductivity is maximized near structural instabilities due to extreme softening of phonon modes responsible for the superconductivity.

The discovery of high T sub c superconductivity prompted an enormous theoretical activity in trying to understand the underlying physics. The situation is, however, still rather unsettled.

Experimental studies are discussed which shed light on the nature of the heavy fermion normal state, the occurrence of heavy fermion superconductivity and anomalous properties of the superconductin

A thermodynamic analysis of the behavior of the lattice parameters and elastic properties at T sub c in the orthorhombic high-T sub c superconductors La sub 2-x Sr sub x CuO sub 4 and YBa sub 2 Cu

We have measured the superconducting and normal state properties of ultra thin quench condensed Pb and Sn films by electron tunneling and transport.

Single-phase fluorinated cuprates M sub 2 CuO sub (4-x) F sub x (M=Pr, Nd) can be prepared up to a limiting composition x approximately equals 0.3-0.4).

Superconductivity in electron-doped C-60 was first observed almost ten years ago.

High temperature superconductivity in layered copper oxides has now been known for more than two years.

An extensive single-crystal study of BaPb(1-x)Bi(x)O(3) over the whole composition range provides new insight in understanding the high superconducting transition temperature in thin oxide.
