Ferro Magnetic

Magnetorheological Fluids (MRFs) are considered as smart fluids because they control viscosity using external magnetic field. It contains ferro-magnetic powder which are aligned in magnetic flux lines. The magnetic force between particles are controlled by magnetic field intensity. This controllable viscosity makes them acceptable in many mechanical applications, but due to difference in density between suspended particles and carrier fluid sedimentation is bound to occur. This thus creates the need of some additives. In our study, silica Nano particles (commercially known as Aerosil 200) is used as stabilizer and Oleic Acid is used as surfactant and their effect on sedimentation is studied in this article. Some other synthesis parameters like particle concentration, stirring duration and material loading also cause some change in sedimentation rate.

The Wire

The object of this paper is to derive two relations in magnetism. In substance they are not new, but in method of statement they are, and the derivation presented here is shorter and simpler than other methods.Consider a ferro-magnetic wire hanging vertically inside a vertical solenoid with heating jacket, a pan being attached to the lower end of the wire for holding weights. Then, if hysteresis be neglected, the state of the wire may be regarded at any time as a function of the three independent variables T, F, and H,—temperature, stretching force, and magnetic field intensity.

Patterned nanostructures and nanodots are attracting increasing interest in the information storage industry. The ultimate recording density of a magnetic medium will have single domain dots aligned in arrays and each dot in such an array acts as a recording bit. The ideal structure is that the dots are magnetic and the surrounding medium is non-magnetic so that each dot can switch magnetization direction freely without the interference from other dots. This paper presents the nanostructure of the nano-dot array investigated by transmission electron microscopy and magnetic force microscopy. The Co:C film was deposited by alternatively sputtering Co target and C target. The as-deposited specimen has an amorphous structure as revealed by electron diffraction in TEM. Such films transform to ferro-magnetic ones after heat treatment [1]. A laser beam of wavelength of 308 nm and a flux of 0.24 J/cm2 was split into two beams of an approximately equal intensity and then recombined, generating an interference pattern and a periodic modulation of the light intensity.
