| Abstract: | We investigated the vortex pinning energies and H(T) characteristic lines of samples with nominal composition MoSr2YCu2O8?δ . The vortex pinning energies were obtained using two approximations of the resistive transition. The characteristic lines H c2(T) and H irr(T) were obtained using resistivity, susceptibility and magnetization measurements. The values of H c2(0) and different irreversibility field values are discussed. |
