Abstract
The effect of aggregate shape on the ultrasonic anisotropy in magnetic fluid was studied. Experimental results were compared with the theory of Ahuja and Hendee. Analysis of experimental results in terms of the theoretical model show the formation of ellipsoidal aggregates composed of several particles. The chain-like aggregates (h = b/a>> 1; a and b being minor and major axis lengths, respectively) are most conspicuous in diluted ferrofluids while dense ferrofluids are characterized by a more homogeneous drop-like (h = b/a>1) structure. This finding is supported by some theoretical simulations.
