Magnetic granularity observed in iron-based films on RABiTS

Local current density maps show the magnetic granularity of iron-based superconductors.

Do grain boundaries in iron-based superconductors have less detrimental effects on the current transport compared to the cuprates? We study the local current transport in iron-based thin films by means of high-resolution scanning Hall probe microcopy and published an article, opens an external URL in a new window with Superconductor Science and Technology in the focus issue “Recent Advances in Superconducting Films”.
