Dendritic flux patterns in MgB 2 films

TL;DR: In this paper, a c-oriented MgB2 film with a critical current density of 107 A cm-2 was analyzed at temperatures below 10 K. The static and dynamic properties of the dendrites were discussed.
Journal ArticleDOI

Magneto-optical imaging setup for single vortex observation

TL;DR: In this paper, a model for the image intensity distribution due to a vortex lattice is developed, and for the intensity profile across a single vortex, the minimum vortex spacing resolved experimentally is 1.3 μm.
Journal ArticleDOI

Localized and delocalized motion of colloidal particles on a magnetic bubble lattice.

TL;DR: This work studies the motion of paramagnetic colloidal particles placed above magnetic bubble domains of a uniaxial garnet film and driven through the lattice by external magnetic field modulation.
Journal ArticleDOI

Origin of dendritic flux patterns in MgB2 films

TL;DR: In this article, the authors observed that the dendrites are formed only in areas lacking the thermal conductor and that when dendritic development in the uncovered part they never invade into the covered region.
