Abstract
The Hc2 - T and the normal resistivity curves of the superconducting RBa2Cu3Oy (R = Eu, Dy, Ho) single crystals are measured from 4.2 K to 300 K under a pulsed magnetic field up to 50 T. The Hc2 - T curves agree well with the WHH theory and the normal resistivities show temperature dependences like normal metal.
