A smart fluids; Magneto rheological, ferrofluid, and nanofluids; a prospect for Medical and Technological applicationBy Gizachew Diga
Abstract: The physiochemical and biomedical applications of smart fluids, typically ferrofluid, magnetorheologicalfluids, and nanofluids are studied. It is predicted that these fluids are impacted by the three most important rheology parameters, namely strain, magnetic field, and temperature. The magnetoresistive contribution is treated in terms of drug force in order to determine thecoefficient of viscosity. The research presents that the viscosity of studied fluids will increase in proportion to applied magnetic field. …

Ferromagnetic Resonance in II-VI Diluted Magnetic Semiconductor, ZnxTM1-xO NanostructuresBy Gizachew Diga
Abstract: The ferromagnetic resonance in II-VI diluted magnetic semiconductor Zn1 xMnxO was studied theoretically. The model employed to manipulate the Hamiltonian of the system which is the Heisenberg Model. By considering a cloud of electron gas and employing equation of state, the fractions of demagnetization factors was determined. For FMR probes, the sample magnetization results from the magnetic moments of dipolar-coupled but unpaired electrons. The resulting frequency versus magnetization curve is …
