Anisotropic thermomagnetic avalanche activity in field-cooled superconducting films
(2017) [Artículo de periódico]The electrodynamic behavior of isotropic superconducting Nb films cooled below their critical temperature in the presence of in-plane applied magnetic fields is investigated using magneto-optical imaging. A specially ... -
Cascade dynamics of thermomagnetic avalanches in superconducting films with holes
(2015) [Artículo de periódico]The submicrosecond dynamics of thermomagnetic avalanches in superconducting films with nonconducting holes (antidots) is considered.When such an avalanche reaches a hole, it is quickly filled with magnetic flux, and often ... -
Crossing fields in thin films of isotropic superconductors
(2016) [Artículo de periódico]We study interactions of perpendicular and longitudinal magnetic fields in niobium films of different thickness in a wide range of temperatures below the superconducting transition temperature (TC). In 100-nm Nb film at ... -
Defects controlling electrical and optical properties of electrodeposited Bi doped Cu2O
(2018) [Artículo de periódico]Doping leading to low electrical resistivity in electrodeposited thin films of Cu2O is a straightforward requirement for the construction of efficient electronic and energy devices. Here, Bi (7 at. %) doped Cu2O layers ... -
Electrodeposited Cu2O doped with Cl : electrical and optical properties
(2018) [Artículo de periódico]For understanding the electrical and optical properties of electrodeposited Cl-doped Cu2O thin films, we have studied layers with increasing thickness and Cl concentrations of 0.8 and 1.2 at. %. The deposits were characterized ... -
Enhancing the effective critical current density in a Nb superconducting thin film by cooling in an inhomogeneous magnetic field
(2021) [Artículo de periódico]Quantitative magneto-optical imaging of a type-II superconductor thin film cooled under zero, homogeneous, and inhomogeneous applied magnetic fields indicates that the latter procedure leads to an enhancement of the screening ... -
Limiting thermomagnetic avalanches in superconducting films by stop-holes
(2013) [Artículo de periódico]It is demonstrated that circular holes in superconducting films of Nb can arrest the propagation of thermomagnetic avalanches. The effect was found over a range of temperatures where the material is susceptible to this ... -
Spin texture on top of flux avalanches in Nb/Al2O3/Co thin film heterostructures
(2017) [Artículo de periódico]We report on magneto-optical imaging, magnetization, Hall effect, and magneto-resistance experiments in Nb/Al2O3/Co thin film heterostructures. The magneto-transport measurements were performed in samples where electrical ...
