Abstract

Abstract The magnetic irreversibility ( T irr ( H)) of a high quality YBa 2 Cu 3 O 7−δ single crystal and two granular superconductors, an YBa 1.5 Sr 0.5 Cu 3 O 7−δ single crystal and a polycrystalline YBa 1.75 Sr 0.25 Cu 3 O 7−δ was determined in great detail up to 50 kOe. The T irr ( H) in the low field region display clear marks of the frustration physics.
