Superconduction: pinning centres by neutron irradiation.

Fast neutron irradiation introduces five nanometre scaled spherical centres of damage. This leads initially to a degradation of the reversible properties of oxide superconductors because their complex crystal structure has a high sensitivity to disorder. But, the resulting pinning centres enhance critical currents.
