摘要：

We have studied the effect of 5.3 GeV Pb irradiation on irreversible magnetic properties of YBa2Cu3O7 crystal, using an ultra-sensitive local Hall-probe technique. In this article we briefly summarize our previous results and present new data at 90 K (= 0.97T(c)) which demonstrate that this type of irradiation enhances flux pinning in the vicinity of T(c).
