Abstract: Analysis has been provided
for the experimental data on ultrasonic absorption in magnetic nanofluids. It was shown for magnetic
nanofluids that experimental data for peaks of ultrasonic absorption coefficient can be explained using the process of magnetic
field relaxation to its equilibrium value in the model of magnetic fluid with
frozen-in magnetization.
Key words: magnetic field relaxation,
magnetic nanofluid, ultrasonic absorption.
