Abstract

We present new measurements of the field distribution in untwinned single crystal of YBa₂Cu₃O₇, using an ultra-sensitive local Hall-probe technique. In the temperature range 75 K to T_c (92.5 K), there is no field gradient along the sample when the external field is reduced. This indicates that Bean-Livingston surface barriers are the main source of magnetic irreversibility in this temperature range.
