Some scientists believe that the breakdown of a property called antiferromagnetism may play a big role in high-temperature superconductivity.
For most materials antiferromagnetism is favored, and the magnetization averages to zero on the length scale of a unit cell, resulting in a weak influence on the superconducting state.

Other Bell Labs papers being presented at the meeting deal with fundamental matters, such as the electronic properties of perovskites, complex oxides that may one day be used widely in industry; X-rays studies of the phenomenon of antiferromagnetism in chromium; and experiments to determine how two-dimensional electron gases behave in low magnetic fields.
