Magnetism helps Electrons Vanish in High-temp Superconductors

The Fermi surface on the left shows the arrangement of electrons in a copper-oxide high temperature superconductor before the “critical point.” After the critical point, the Fermi surface on the right shows that most electrons vanish. Research by the Brad Ramshaw’s lab connects this disappearance with magnetism.

A physicist’s discovery could lead to the engineering of high-temp superconducting properties into materials useful for quantum computing, medical imaging.

Superconductors — metals in which electricity flows without resistance — hold promise as the defining material of the near future, according to physicist Brad Ramshaw, and are already used in medical imaging machines, drug discovery research and quantum computers being built by Google and IBM.

However, the super-...
