THE EFFECT OF OXYGEN DEPLETION ON THE INPLANE RESISTIVITY AND HALL-COEFFICIENT OF CRYSTALLINE THIN-FILMS OF YBA2(CU1-XZNX)(3)O-7-DELTA

The different effects of in-plane or out-of-plane doping on the normal state transport properties of fully oxygenated YBCO are fairly well e stablished. Little is known, however, about the effects of in-plane im purities on oxygen deficient or underdoped YBCO. To address this issue we report measurements of RH(T) and rho(ab)(T) of laser ablated cryst alline thin films of YBa2(Cu1-xZnx)(3)O-7-delta with 0 less than or eq ual to x less than or equal to 0.02 and 0 less than or equal to delta less than or equal to 0.28, and discuss our results in relation to rec ent specific heat measurements by Loram and co-workers.
