Analysis of the measurements of anisotropic a.c. vortex resistivity in tilted magnetic fields
, 2017 Measurements of the high-frequency complex resistivity in superconductors are a tool often used to obtain the vortex parameters, such as the vortex viscosity, the pinning constant and the depinning frequency.

Peak effect in twinned superconductors [PDF]
, 1995 A sharp maximum in the critical current $J_c$ as a function of temperature just below the melting point of the Abrikosov flux lattice has recently been observed in both low and high temperature superconductors.

Slight Truncation Changes in Iron Oxide Nanocubes Strongly Affect Their Magnetic Properties
Advanced Functional Materials, EarlyView.Subtle variations in nanoparticle morphology can lead to significant changes in functional properties. An automated shape‐fitting method captures minor differences in corner truncation between iron oxide nanocubes of similar sizes synthesized under identical conditions, revealing pronounced disparities in their magnetic and hyperthermia behavior ...

Effects of columnar pins on flux line dynamics
Physical Review Letters, 1993 The effects of columnar pins on the flux lines in a model High-Tc superconductor in an applied field are studied through Monte Carlo simulations. An analytic solution for a single line case is obtained and compared with the simulation results. By introducing a tilted potential, we study simulated ``IV" characteristics and the results indicate a ...

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry
Advanced Functional Materials, EarlyView.In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

Flux pinning characteristics in superconductors.
TEION KOGAKU (Journal of Cryogenics and Superconductivity Society of Japan), 1989 The critical current density is an important factor as well as the critical temperature and the critical magnetic field in power application of superconductors. A magnitude of the critical current density is determined by flux pinning interactions. In this report the flux pinning phenomenon is briefly explained and it is discussed what is to be done ...
