Kopsavilkums

We submit a magnetic fluid to a solid rotation and analyze the free precession decay of its transverse magnetization and of its nondiagonal optical anisotropy. In agreement with the theoretical predictions, they present damped oscillations because the magnetic particles rotate, dragged by the carrier angular velocity. The node period is inversely proportional to vorticity. We show that magnetic particles can be used as advanced nanoscopic tools to probe neatly the vorticity of their fluid carrier.
