A new experiment offers the cleanest proof yet for magnetism-driven transitions of metals to insulators. Like all metals, silver, copper, and gold are conductors. Electrons flow across them, carrying ...

University of Cambridge researchers have discovered that a material already known for its peculiar electrical properties appears to behave as both a conductor and an insulator at the same time. This ...

Researchers have identified a material that behaves as a conductor and an insulator at the same time, challenging current understanding of how materials behave, and pointing to a new type of ...
