Abstract
As a new magnetoresponsive magnetorheological MR material under an applied magnetic field magnetic Fe nanoparticles were synthesized from a simple process of thermal decomposition of pentacarbonyl iron using oleyl amine and kerosene at 150 °C Morphology of the fabricated Fe nanoparticle was examined using both scanning electron microscopy and transmission electron microscopy MR characteristics of the nanosized magnetic particlebased MR fluid dispersed in nonmagnetic carrier fluid was investigated using a rotational rheometer under different external magnetic field strengths focusing on their flow behaviors at a steady shear mode and yield stress Flow curve was also found to be fitted well with the Casson equation
