Flux avalanche is commonly found in type II superconductors, and this event is always
featured as being unpredictable and having ultrafast development with time. It is difficult to …

We analyzed the distribution of the Meissner shielding currents in a flat superconducting ring
and quantitatively described the penetration of magnetic avalanches (dendrites) inside it …

Magneto-optical imaging of Nb rings, open rings, and strips reveals that the topology affects
the dendritic flux avalanches in the samples. In particular, dendrites crossing the entire width …

Magnetic vortices resemble bowstrings stretched across a corner at the initial stage of their
penetration into a flat superconducting sample of a rectangular cross-section. As the …

Niobium Nitrate (NbN) superconducting films are extensively used in superconducting
electronics, for example as a basic element of single-photon microwave resonators. Here we …

Background Vortex stability is critically important for applications of type-II superconductors.
If some vortices are detached from their pinning sites by external perturbations, the …

Magneto-optical imaging is a powerful technique for studying qualitative features of
magnetic flux distributions in superconductors and other magnetic samples. However …
