For the purpose of plotting the H-T diagram for MgB₂ granular superconductors, the behavior of electrical resistivity-versus-temperature dependences were studied at ~35 to ~45 K in external magnetic fields with magnetic field strengths Hext up to ~2 kOe. The effect of increasing the superconductivit...
