Abstract

The temperature and angular dependence of the irreversibility field of YBa₂Cu₃O_y (6.6≤y≤6.9) single crystals have been investigated by magnetic measurements in magnetic fields up to 55kOe. The angular dependence of H_irr is well described by the expression, H_irrlnH_irr∝1/(cos²θ+γ^-2sin²θ)^{1 2}, which is expected from the flux creep model. The γ value is in good agreement with the effective mass ratio obtained from the angular dependence of the resistive transition.
