Variation in energy stored and dissipated in type-II superconductor in applied ac magnetic field with relative phase of two sinusoidal components of the field
Zdenek Janu, Tymofiy Chagovets
We show that both the energy stored and dissipated by a system with hysteretic nonlinearity in an applied field varies with the relative phase of the sinusoidal components of the f…
Reduction in energy dissipation rate with increased effective applied field
Zdenek Janu, Frantisek Soukup
Dynamics of the response of type-II superconductors to a time-varying magnetic field can exhibit a rate-independent or rate-dependent hysteresis. An energy dissipation rate in a su…
Low-Temperature Magnetic Anomaly in Magnetite
Zdenek Svindrych, Zdenek Janu, Andrzej Kozlowski +1
We have studied experimentally the responses of high quality single crystals of stoichiometric synthetic magnetite to applied weak dc and ac magnetic fields in the range of 6 K to…
Contactless estimation of critical current density in thin superconducting films and its temperature dependence using ac magnetic measurements
Ahmed Youssef, Lucia Banicova, Zdenek Svindrych +1
We have measured magnetic response of second-generation high temperature superconductor YBa2Cu3Ox wire and Nb thin film in perpendicular ac field as a function of temperature. We c…
Analysis of Critical State Response in Thin Films by ac Susceptibility Measurements
A. Youssef, Z. Svindrych, J. Hadac +1
Harmonic analysis of the temperature dependence of the nonlinear ac susceptibility of Nb thin film gives excellent agreement with the susceptibility calculated on basis of model of…
Quasiparticle scattering in superconductors
Zdenek Janu, Frantisek Soukup, Rudolf Tichy +3
We compare results of high-resolution magnetic flux (susceptibility) measurements in very weak magnetic field, performed of three classes of superconductors. They reveal astonishin…
