摘要：

Moving- and stationary-sample SQUID magnetometry indicates discontinuous jumps of the magnetization of an untwinned single crystal of YBa2Cu3O7-delta. The location of these jumps in the H-T plane coincides with the location of the resistive drops measured on the same sample. These results demonstrate the existence of a first-order melting transition of the flux line lattice in YBa2Cu3O7-delta.
