Unusual (Anomalous) Properties of the Normal and Superconducting State of Cu-Oxides
Although the superconducting Cu-oxides are essentially metals, their normal-state properties are markedly different from those of common metals and it is argued that new theoretical concepts are needed for their description. The reason for the occurrence of superconductivity in these materials at relatively high temperatures is still unknown and debates with respect to triggering mechanisms and characteristics of the superconducting state continue. Below we briefly review experimental data that reflect anomalous behaviour, but we also mention observations that are compatible with conventional models of normal and superconducting states of metals.
