Abstract

By low‐temperature transmission electron microscopy we have found nanodomains in a polycrystalline Nb~3~Sn sample. We interpret that these nanodomains form due to a tetragonal distortion. Because twinning seems to be a prominent feature of the real structure of many high T~c~ superconductors, possible interactions between a twinned structure and superconductivity are briefly discussed.
