• We present angular-dependent current-voltage (I-V) measurements in borocarbide YNi2B2C single crystals near the vortex-glass irreversible line. External magnetic fields are applied along the angle theta with respect to the c-axis. The nonlinear I-V curves reveal scaling behaviour near the transition. Using the scaling analysis, the relevant critical exponents and vortex transition temperatures are determined for all orientations. The data agrees well with the vortex-glass (VG) model. No evidence was found that supports the existence of a Bose-glass (BG) type of transition.
