英文摘要	Using a 200 kev electron beam with the intensity similar to 7 x 10(16) e nm(-2) as an irradiation source, we investigated the irradiation effects on the microstructure of a new superconductor, sr2cuo2+deltacl2-y, by means of high-resolution transmission electron microscopy, electron energy loss spectroscopy (eels) and energy dispersive analysis of x-rays (edx). when the sample was illuminated along the [001] direction, a kind of modulated structure with modulation vector q = (2 pi/a(p)) (+/- 1/10, 1/5, 0) and wavelength lambda = similar to 8.81 angstrom was found to develop, while when the sample was illuminated along the [100] direction, there was no evidence of a transition of the modulated structure. the o k, cu l-2,l-3 eels spectra and edx data suggest that the modulated structure results from an ordered oxygen deficiency and the o vacancies are suggested to be located in the cu-o plane.
