✦ Synopsis

Ultrasonic attenuation in single crystals of superconducting tin is affected by the presence of strain and impurities. The effect of different pulse ampfitudes on attenuation in pure and impure single crystals has been studied for strained and annealed specimens. It was found that, at different amplitudes, oscillations are always present in an impure specimen, but in a pure specimen, small ampfitudes favour oscillation. The temperature dependent attenuation is also strongly dependent on the strain content of the specimen and the ampfitude.
