ELECTRONS WITH DRAG
Condensed-matter physicists have studied the thermal and electronomagnetic properties of metals for several decades and believed they had a fair understanding of them. In the last few years, however, they have been surprised by the discovery of a number of metal compounds in which such properties as specific heat and electrical conductivity behave very strangely. Among the more striking findings is a seemingly new kind of superconductivity, which seems to have a different origin from ordinary superconductivity and to be compatible with magnetism in ways that ordinary superconductivity isn't (SN: 4/7/84, p. 212).
The metals in ...
