Abstract
Sound velocity measurements in Ni-P are reported. The velocity of longitudinal and transverse waves has been measured at 70 MHz and 150 MHz down to 0.37 K. At low temperatures (below 2 K) the velocity follows a logarithmic temperature law as in amorphous insulators. At higher temperatures the velocity decreases linearly as the temperature is increased up to 30 KKeywords
