Аннотация: It was found that high-temperature superconductor (HTSC) based composites of the 1-2-3 (YBCO) + dielectric and YBCO + normal metal types exhibit large magnetoresistances in weak magnetic fields in a broad temperature range. This behavior is qualitatively explained using the concept of the irreversibility line in HTSCs and the mechaПоказать полностьюnism of thermal fluctuations in the network of weak bonds of the Josephson type realized in HTSC composites. The HTSC-based composites exhibit a much higher sensitivity (as compared to that in the usual HTSC ceramics) to weak magnetic fields (below 300 Oe) at liquid-nitrogen temperatures, which is important for practical applications.
