The book comprises six chapters which deal with the critical currents and the ferromagnetism-superconductivity coexistence in high-Tc oxides. It begins by gathering key data for superconducting state and the fundamental properties of the conventional superconductors, followed by a recap of the basic theories of superconductivity. It then discusses

Applications of superconductivity at the boiling temperature of liquid nitrogen continue to challenge physicists, materials scientists and engineers all over the world eight years after the discovery of high temperature superconductivity. The key to a solution of today's problems lies in the optimization of the defect structure in well-oriented oxide materials as well as in a fundamental understanding of the magnetic microstructures in the mixed state and how they are affected by the crystallographic nature ('dimensionality') of these materials. Fifteen invited overview lectures as well as approximately 150 contributed papers highlight the state of the art in this important field of superconductivity and review our current knowledge of critical currents in superconductors.

This volume will focus on the theory and experiments leading to quantitative understanding of the magnetic field and temperature dependence of critical current densities in high-temperature superconductors. Topics will include: critical currents and flux-pinning, flux flow and flux creep, anisotropy of critical fields and currents, properties of the flux lattice and the irreversibility line, magnetization, granularity.

This authoritative book provides a deeply informed overview of contemporary Indigenous movements in Ecuador. Leading scholar Marc Becker traces the growing influence of the Confederation of Indigenous Nationalities of Ecuador (CONAIE) in the wake of a 1990 uprising, the launch of a new political movement called Pachakutik in 1995, and the election of Rafael Correa in 2006. Even though CONAIE, Pachakutik, and Correa shared similar concerns for social justice, they soon came into conflict with each other. Becker examines the competing strategies and philosophies that emerge when social movements and political parties embrace comparable visions but follow different paths to realize their objectives. In exploring the multiple and conflictive strategies that Indigenous movements have followed over the past twenty years, he definitively charts the trajectory of one of the Americas' most powerful and best organized social movements.

The book deals with the flux pinning mechanisms and properties and the electromagnetic phenomena caused by the flux pinning common for metallic, high-temperature and MgB2 superconductors. The loss originates from the ohmic dissipation of normal electrons in the normal core driven by the electric field induced by the flux motion. Readers will learn why the resultant loss is of hysteresis type in spite of such mechanism.
