Phenomenological Model Fit to Intragranular Ac Susceptibility of Sintered High-,, Superconductorsentry and exit has been developed,. providing a tool to analyse the high-field hysteresis loops of sintered high-.. superconductors. In the present paper we introduce a technique to analyze the intragranular ac susceptibility of these materials based on a similar model.

Detailed Theory of the Magnetic Response of High-Temperature Ceramic Superconductorsng grains and the pinning of Josephson vortices which form along grain boundaries, producing an intergranular field. For strong magnetic fields Abrikosov-like vortices form inside grains and generate an intragranular field.

Utility of the χac Response in the Low Field Limit for Characterizing Inhomogeneous Superconductorses, thin films, single crystals, powders), stoichiometry, coexistence of several phases, field orientation, etc... One can thus easily understand the difficulty encountered in comparing results obtained in different labs, using various experimental techniques applied on samples of different shapes!
