Vortex Dynamics in the High-Temperature Superconductors YBa2Cu3O7 and Bi2Sr2CaCu2O8+[delta] in Low- and High-Dissipative Transport Measurement
Author: Patrick Voss-de Haan
Publisher: Ibidem Press
ISBN: 9783898210249
Category : Science
Languages : en
Pages : 150
Book Description
Since their discovery in 1986, high-temperature superconductors (HTSC) are considered interesting physical systems as well as attractive candidates for a variety of technical applications. In both cases one of the key aspects to be understood is the mechanism of power dissipation, which depends primarily on vortex dynamics: the movement of magnetic flux lines in the superconductor when a transport current is applied. The present work studies vortex dynamics in experiments on two of the most prominent types of HTSC materials, YBa2Cu3O7 (YBCO) and Bi2Sr2CaCu2O8+d (BSCCO), in the limit of low and high current densities. Both, the applied transport current density and the dimensionality of the materials, strongly influence the dynamic response. For the low current limit in BSCCO this thesis concentrates on the influence of oxygen stoichiometry and in YBCO on a vortex glass phase, which indicates a true superconducting state with vanishing linear resistivity. In the high current limit, for the first time, a vortex instability is shown to exist in BSCCO, apparently arising from a fluid phase, while a similar phenomenon in YBCO reveals a clear correlation of the high-dissipative instability to the low-dissipative vortex glass phase. The author: A native of Hamburg, Germany, Patrick Voss-de Haan studied physics at Stanford University and the University of Mainz. After completing a degree in the area of atomic physics and laser spectroscopy he began his work in solid state physics and superconductors, from which this Ph.D. thesis was compiled.

Physics and Materials Science of Vortex States, Flux Pinning and Dynamics
Author: R. Kossowsky
Publisher: Springer Science & Business Media
ISBN: 9780792356646
Category : Science
Languages : en
Pages : 792
Book Description
A discussion by an assembly of expert physicists and materials scientists, embracing the specific features of vortex-pin interactions, the modes of different kinds of vortex motion under the action of Lorenz force, and the mechanisms of dissipation. The effects of transport and screening currents, superimposed AC magnetic fields and the microwave electromagnetic irradiation on vortex behaviour define the electromagnetic properties of a high-Tc superconducting material. The mechanisms driving the depinning of vortices and the dynamics of their motion determine the critical current density and its file dependence, the mechanisms of energy dissipation, and linear and nonlinear resistivity, AC losses, and noise in electronic circuitry. The book therefore has direct implications for the development of new devices and components in electrical engineering, modern electronics, computer technology, and microwave communication.

The Vortex State
Author: N. Bontemps
Publisher: Springer Science & Business Media
ISBN: 9401109745
Category : Science
Languages : en
Pages : 330
Book Description
One of the most spectacular consequences of the description of the superfluid condensate in superfluid He or in superconductors as a single macroscopic quantum state is the quantization of circulation, resulting in quantized vortex lines. This book draws no distinction between superfluid He3 and He4 and superconductors. The reader will find the essential introductory chapters and the most recent theoretical and experimental progress in our understanding of the vortex state in both superconductors and superfluids, from lectures given by leading experts in the field, both experimentalists and theoreticians, who gathered in Cargèse for a NATO ASI. The peculiar features related to short coherence lengths, 2D geometry, high temperatures, disorder, and pinning are thoroughly discussed.
