Abstract
Experimental results for the DC magnetic field influence on the anisot ropy of attenuation of ultrasound in ferrofluids are presented. The me asurements were performed for the frequency 1.18 MHz, at the temperatu res 10 and 40 degrees C, with magnetic field strengths H = 39.8, 79.58 and 159.15 kA m(-1). Comparison of the experimental results with the Taketomi theory allowed the determination of the cluster radius and th e number density of the colloidal particles.
