摘要：

Thin films of c-axis and a-axis oriented REBa2Cu3O7-delta (RE = Y, Gd, Eu) deposited by magnetron sputtering were irradiated with H+, He+ and Ar2+ ions. The changes of the transport properties were studied as a function of the crystal direction, the angle of incidence and the ion mass. The T(c)-depression rates are lowered for aligned ion irradiation due to the reduced nuclear energy loss of the channeled particles. For off-axis irradiated a-axis and c-axis oriented thin films the T(c) depression rates are similar; however, they are quite different for H+ and Ar+ ion irradiated samples. This is attributed to different defect structures which are probably also responsible for the different temperature dependence of rho which is proportional to exp(T-1/4) or approximately exp(T-1) in the metal to insulator transition regime for Ar2+ and H+ ion irradiation, respectively. Channeling measurements on YBa2Cu3O7-delta single crystals at various temperatures and damage levels showed that the main contribution to the irradiation reduced Debye temperature is of static nature.
