Abstract
We demonstrate the use of acoustic microscopy in investigation of both local acoustic properties of individual crystallites and various defects in HTSC-materials. It is important that the acoustic microscopy provides for: (a) viewing the defects in the depth of a non-transparent sample, unlike the optical methods; (b) determining the Rayleigh wave velocity on a small (~10 μm) section of surface (for example, on an individual crystallite); (c) detection of defects in the presurface layer by attenuation of such waves. In our work we used a commercial acoustic microscope ELSAM (Ernst Leitz Scanning Acoustic Microscope) [1].
