Scientists have recently discovered a new group of metals. The newly discovered Metal group is called as New Strange group of metals. The characteristics of metals like copper or iron are predictable. That is, their melting point, reaction nature, malleability, ductility are known to human. The characteristics of this new group of metals are yet to be deciphered. They still remain a puzzle. Thus, these metals have been classified as strange metals.
The strange metals are also called non Fermi liquids. They do not follow the traditional rules of metals. Their behavior was first discovered in cuprates, that is, copper oxides. These cuprates are high temperature super Conductors.
The strange metals do not conduct electricity as that of metals. In metals, the electrical charge is carried by electrons. In strange metals, the electrical charge is carried by Cooper pairs. These cooper pairs take the charge in wave like pattern. Electrons belong to fermion. The cooper pairs act as bosons.
