摘要
A melt-textured bulk YBa2Cu3O7-x sample has been investigated by magnetization M(H) and magneto-resistance R(H) measurements in pulsed magnetic fields up to 50 T. We describe a technique which allowed us to determine the irreversibility fields H-irr from M(H) and R(H) curves. The irreversibility line shows linear behavior in the fields above 20 T which cannot be explained by present models. (C) 2004 Elsevier B.V. All rights reserved.
