Abstract

Microstructures of bulk and thin film YBa ₂Cu ₃O _7-δ superconductors were studied by using scanning electron microscopy (SEM). It was confirmed that viscous technique processed bulk YBa ₂Cu ₃O _7-δ has a homogeneous microstructure across the pellet diameter. Concerning the thin film, it was found that ²H ⁺ ion implantation with a dose of 1×10 ¹²cm ^-2 at 50 keV does not cause microstructural change of the film at a micrometre level. Combined with previous studies by using high resolution transmission electron microscopy, it appears that the structural modification is at an atomic scale.
