- The in-plane resistivity of an oxygen deficient YBa2Cu3O7-delta single crystal has been measured as a function of magnetic field B \\ c-axis in the range 0 T less than or equal to B less than or equal to 12 T. A scaling relation is found for the linear resistivity at p less than or similar to 0.1 rho(n) above the glass line that incorporates all studied temperatures and magnetic fields. Our scaling can be understood within a simple model where the mean pinning energy balances the thermal energy at the glass transition, U-0(B, T-g) = k(B)Th(g), with U-0(B, T) resembling a generalized condensation energy, U-0 similar to (1 - T/T-c)(m)/B-beta.
