Superconductors with zero electrical resistance?


This is a New Scientist exclusive.
Superconductivity is creating a buzz again with the announcement of a new material that is said to have zero electrical resistance at room temperature.

The claim, from researchers in Croatia, comes just a few weeks after the discovery that the simple chemical magnesium diboride superconducts at temperatures up to almost twice those needed for other metallic superconductors to work (New Scientist, 3 March, p 6).

The Croatian scientists say that current will flow effortlessly through their material, a mixture of lead carbonate and lead and silver oxides, at up to about 30 °C.

But because of numerous false alarms in this field, researchers are treating the announcement with caution, especially as no one has yet managed to reproduce the results.
