Аннотация: The results of the study of transport properties (temperature dependences of resistivity and critical current, current-voltage characteristics) of two-phase composites on the basis of Y3/4Lu1/4Ba2Cu3O7 high-temperature superconductor (HTSC) produced by fast baking technique and modelling networks of Josephson-type weak links are reПоказать полностьюported. Non-superconducting ingredients with different magnetic structures, insulators and normal metals, function as barriers between HTSC crystallites. Besides strong suppression of superconducting properties in HTSC composites with magnetic barriers, anomalous behavior of temperature dependences of resistivity below T-c of HTSC grains have been observed and investigated.
