| Abstract(in English) | BiSrCaCuO thin films were deposited by ion assisted IBS to obtain-superconducting 2212 phase.A target of BiSrCaCuO ceramic was sputtered on MgO(100) substrate at oxygen partial pressures of l-3XlO^-4> Torr at substrate temperatures of 600-700℃.During the film growth,the substrate was irradiated by the assisting ions of O^+,and its effect was examined.A scattering of film composition can be reduced by increasing the oxygen pressure.The films are amorphous without assisting,however 2201 crystal phase is grown by assisting.When the assisted films are annealed at 800℃,the 2212 cr ystal phase is grown.This film shows superconducting ρ-T character istics and T_c,ON>=91K.The growth of the 2212 phase is promoted by annealing at 820℃ and the film shows T_c,ZERO>=93K.However,whe n the non-assisted films are annealed by the same way impurity phase are only grown and they show no superconducting properties. Promotions of a surface migration and oxydation are expected as effects of the ion assisting. |
