Persistent supercurrents in MgB2

Persistent currents were induced in rings of superconducting granular MgB2. We measured the magnetic self-fields generated by these currents using a scanning Hall probe. We obtained both the temperature dependence of the persistent current at the critical level between 15 K and Tc (39 K) and the tim...
