Intense vortex pinning enhanced by semicrystalline defect traps in self-aligned nanostructured MgB2

Intense vortex pinning enhanced by semicrystalline defect traps in self-aligned nanostructured MgB2

In this work, we report the discovery of a vortex pinning source: semicrystalline defect wells in self-aligned nanostructured MgB2. It is demonstrated that these aperiodic regions trap numerous crystal defects migrating along nanodomain boundaries during self-alignment and act as intense vortex pinn...
