Electron microscope image of a chromium dioxide devices based on wires. The green wire is the chromium dioxide ferromagnet. The orange wires are superconductors and are necessary to produce a superconducting current through the green wire.

Electrons that spin synchronously around their axis, turn out to stay superconductive across large distances within magnetic chrome dioxide. Electric current from these electrons can flip small magnets, and its superconductive version could form the basis for a hard drive without energy loss...

This corresponds to half of the pressure of Earth’s core. With their high-pressure experiments the Mainz researchers have thus not only set a new record for superconductivity, their findings have also highlighted a potential new way to transport current at room temperature with no loss.

For many solid-state physicists, superconductors that are suitable for use at room temperature are still a dream. Special copper oxide ceramics, so-called cuprates, took the leading positions in terms of transition temperature, i.e., the temperature at which the material loses its resistance. The record for a ceramic of this type is roughly -140C at normal air pressure -109C at high pressure. In the ceramics, a special, unconventional form of superconductivity occurs...
