Iron-rich lamellae in a semiconductor

There is often a pronounced symmetry when you look at the lattice of crystals: It doesn't matter where you look—the atoms are uniformly arranged in every direction. This behavior would also be expected of a crystal, which ...

Linking superconductivity and structure

Superconductivity is a rare physical state in which matter is able to conduct electricity—maintain a flow of electrons—without any resistance. It can only be found in certain materials, and even then it can only be achieved ...

Quantum fluctuations are key in superconductors

(PhysOrg.com) -- New experiments on a recently discovered class of iron-based superconductors suggest that the ability of their electrons to conduct electricity without resistance is directly connected with the magnetic properties ...
