Superconductors Show Their Stripes

Phys. Rev. Focus 9, 12 (2002) – Published February 27, 2002

Charge ‘stripes’ have been observed in the most widely studied high-temperature superconductor, bolstering a theory that says they’re the key to carrying electricity without resistance.

Melting in a Superconductor

Phys. Rev. Focus 7, 2 (2001) – Published January 19, 2001

New evidence confirms that the lattice of so-called magnetic vortices in a superconductor can melt, just like a real solid. The vortices directly affect the amount of electric current a superconductor can carry.

New Info from Slow Muons

Phys. Rev. Focus 5, 22 (2000) – Published May 15, 2000

A new precision technique confirms that the magnetic field penetrates a superconductor only a few hundred nanometers below the surface in exactly the way theory predicts.
