Development of Magnetorheological Elastomer System for Adaptive Vibration Isolation
… featuring magnetorheological elastomers (MREs). MREs were utilized to generate adaptability (variable stiffness) to the AB system. The investigations of this project were fundamental and developmental studies ranging from material synthesis, material characterization, theoretical studies, …

Mechanics of magneto-active polymers
… <p>Second, the mechanism of the stiffening effect in magneto-rheological elastomers (MREs), a class of anisotropic MAPs, is investigated. MREs tend to be mechanically stiffer under a magnetic field. Such a stiffening effect is usually referred to as the magneto-rheological (MR) effect and …

Characterisation and Modelling for Elastomeric and Gel-Like Magnetorheological Materials
Magnetorheological (MR) material is an aspiring branch of smart material. It can change its mechanical properties rapidly and reversibly subjected to an externally applied magnetic field, so-called MR effect. Due to the sensitivity to magnetic field and the versatility in physical states, i.e., …

Structural and magnetotransport study of SrTiO3-δ/Si structures grown by molecular beam epitaxy
… dependence, we consider several competing effects in STO/Si such as 1.7% compressive strain induced by lattice mismatch with Si, strain and defects due to oxygen vacancies, an antiferrodistortive phase transition at 105K in bulk STO, and structural dislocations. We find that a charged space …

Magneto-transport properties of manganite/secondary phase inhomogeneous systems
We have studied the artificial granularity effect on related properties in manganites, by introducing secondary phases into a ferromagnetic manganite forming an inhomogeneous manganite/secondary phase system. TiO2 insulator was introduced as a secondary phase into the ferromagnetic La0.7Ba0.3MnO3 …

Phase Coexistence in Manganites
… and La0.60Ca0.40MnO3 films is investigated. The effect of an external magnetic field is studied. A high-field magnetoresistance (∆ρ/ρB=0) of 41% in fields of 400 mT was observed for a La0.60Ca0.40MnO3 film, which, while not as large as the values previously reported in the literature, is still …

The behaviour of magnetorheological fluids in squeeze mode
Magnetorheological (MR) fluids possess rheological properties, which can be changed in a controlled way. These rheological changes are reversible and dependent on the strength of an excitation magnetic field. MR fluids have potentially beneficial applications when placed in various applied loading …
