Attenuation of ultrasound has been measured in the intermediate state of single crystals of tin at 3.3 MHz in the temperature range 1.5-3.7 K. A small measurable change of the frequency v o of the collective modes of excitations has been observed very near the critical magnetic field.
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 ampl
