Effect of the Temperature, External Magnetic Field, and Transport Current on Electrical Properties, Vortex Structure Evolution Processes, and Phase Transitions in Subsystems of Superconducting Grains and “Weak Links” of Granular Two-Level High-Temperature Superconductor YBa{sub 2}Cu{sub 3}O{sub 7–δ}

The temperature dependences of the resistivity of granular high-temperature superconductor YBa{sub 2}Cu{sub 3}O{sub 7–δ} ρ(T) are measured at various transverse external magnetic fields 0 ≤ H{sub ext} ≤ 100 Oe in the temperature range from the resistivity onset temperature T{sub ρ=0} to the supercon...
