Occasionally, in pulsed ultrasonic attenuation measurements, oscillations in the amplitude of the received sound signal are observed, when a certain parameter (temperature or magnetic field) is varied. Sometimes these oscillations in the received signal amplitude are of spurious origin, (that is, they have nothing to do with any attenuation mechanism within the sample under investigation). In this paper we discuss two examples of oscillatory behavior in ultrasonic attenuation that we have seen when the magnetic field was varied; one real, the other spurious.
