Abstract We report on the temperature and field dependence of the ac susceptibility and magnetic hysteresis of a number of YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} single crystals with very low twin boundary densities and with defects added in a controlled manner to the crystal surfaces. It is shown that surface damage is by far the most important source of flux pinning, and that substantial shifts in the irreversibility line can be controlled by the number and type of defects added to the surface.
