Size of flux jumps in superconducting films

D. V. Shantsev, A. V. Bobyl, Y. M. Galperin +2

Magneto-optical imaging is used to visualize vortex avalanches in MgB2 films at 4K. Avalanches ranging from 50 to 50000 vortices were detected. The size distribution function has a…

Magnetostrictive behaviour of thin superconducting disks

Tom H. Johansen, Daniel V. Shantsev

Flux-pinning-induced stress and strain distributions in a thin disk superconductor in a perpendicular magnetic field is analyzed. We calculate the body forces, solve the magneto-el…

Direct Demonstration of the Anisotropic Origin of the Macroturbulent Instability in Type-II Superconductors

L. M. Fisher, A. Bobyl, T. H. Johansen +4

The physical nature of the macroturbulence in the vortex matter in YBCO superconductors is verified by means of magnetooptic study of the instability in a single crystal prepared s…

Optical detection of magnetic data using magnetooptic indicators with in-plane magnetization

L. E. Helseth, E. I. Il'yashenko, M. Baziljevich +1

We investigate detection of magnetic data using magnetooptical indicators with in-plane magnetization. A simple model for the magnetooptical detection system is presented. We find…

Direct Observation of Coexistence of Ferromagnetism and Superconductivity in RuSr2(Gd0.7Ce0.3)2Cu2O10

S. Y. Chen, J. Shulman, Y. S. Wang +6

Recent reports of the detecting of ferromagnetism and superconductivity in ruthenium-cuprates have aroused great interest. Unfortunately, whether the two antagonistic phenomena coe…

Comparison of flux creep an nonlinear E-j approach for analysis of vortex motion in superconductors

D. V. Shantsev, A. V. Bobyl, Y. M. Galperin +1

Two commonly accepted approaches for simulations of thermally-activated vortex motion in superconductors are compared. These are (i) the so-called flux creep approach based on the…
