摘要：

The negative magnetoresistance was observed in flux-grown single crystal Y0.70Pr0.30Ba2Cu3O7-y with magnetic field applied either perpendicular or parallel to the ab plane up to 15 T. The magnetoresistance was saturated at 8 T after which it started increasing. The observed negative magnetoresistance may be due to the 2-D weak localization of charge carriers.
