«How to maximize
the superconducting critical temperature in a molecular superconductor.»
An international research team, led by Professor Kosmas Prassides of Tohoku University, has investigated the electronic properties of the family of unconventional superconductors based on fullerenes * 1 which have the highest known
superconducting critical temperature (Tc) among molecular superconductors * 2.

Thanks to quantum - mechanical effects, below a certain
critical temperature some materials become
superconducting: electrons flow through them unhindered by the usual electrical resistance.
This
critical temperature is rather low compared to e.g. fullerenes which
superconduct at 33K.
Superconducting materials exhibit an invaluable feature when cooled below a
critical temperature — they allow the transport of an electric current without loss.
Now, a team of scientists has come up with a way to double the amount of electrical current an iron - based material can carry without losing its
superconducting properties, while increasing the material's
critical temperature.
«Below a
critical temperature, electrons in the material act in a fundamentally different way, and it starts
superconducting,» says Beck.
«We were selected to provide
critical technologies that generate the high - brightness and high - repetition - rate electron beam that is the first component in the
superconducting accelerator chain, and the undulators that are the core of the free - electron laser X-ray source.
