Summary:  1999 PhotoDisc, Inc.
Miraculous metal. Thin sheets of
aluminum are excellent for containing
beverages, but they also have surprising
properties at low temperatures. Under
certain conditions, ultrathin aluminum films
require heating to become
superconducting.

Title and Authors
Warming Up to Superconductivity
Many metals dramatically lose all
electrical resistance when they are chilled
to low temperatures. But the 1 November
PRL describes a case where
superconductivity can arise from heating
the sample, if it starts out cold enough.
The researchers also found another
