Abstract :
The authors have measured the upper critical magnetic field H c2 of single crystals of the high-Tc superconductors YBa2Cu3O7 and NdBa2Cu3O7 as a function of crystal orientation in DC fields up to 31.5 T. The temperature dependence and anisotropy of Hc2 and inferences concerning spin-orbit scattering are discussed. The lowest value of critical field is obtained for the crystal orientation which makes the applied field perpendicular to the Cu-O planes and is not much different from the values of Hc2 for some conventional superconductors
