Abstract
Magnetorheological (MR) fluids with Fe3O4 particles are widely studied nowadays due to their soft magnetic nature, controllable morphology, and better chemical stability as compared to their metallic counterpart. However, they can be even more advantageous under Zn doping with elevated magnetization and hollow configuration with low density, making them more active, stable, and dispersible in the carrier fluid. Here, we report the preparation of MR fluids with Zn0.2Fe2.8O4 sub-micrometer hollow spheres and their steady-state MR response under the application of a magnetic field. The MR fluid follows the Bingham plastic nature with a yielding behavior. The variation of yield stress with the applied magnetic field is explained in the context of a newly developed dipolar interaction model. © 2021 Author(s).
