  • Effect of magnetic field on the electrodeposition of FeCo layers has been investigated with respect to the orientation of the magnetic field to surface electrode e.g magnetic field is parallel and perpendicular to electrode. Electrochemical behaviours, morphology, composition, structure and magnetic properties were investigated using cyclic voltammogram (CV), Scanning Electron Microscopy (SEM), Energy Dispersion Spectroscopy (EDS), X-Ray Diffractometer (XRD), Vibrating Sample Magnetometer (VSM).

  • The Hall effect is studied theoretically in a doped semiconductor superlattice (DSSL) subjected to a crossed dc electric field and magnetic field in the presence of an intense electromagnetic wave (EMW). By using the quantum kinetic equation for electrons interacting with acoustic phonons at low temperature, we obtain expressions for the magnetoresistance as well as the Hall coefficient in dependence on the external fields and characteristic parameters of the DSSL. Analytical results are numerically evaluated for the GaAs:Si/GaAs:Be DSSL.

  • This investigation was carried out under an external magnetic field fixed at 4 kOe to ensure for all the Co-granule magnetization being kept in a fixed incident light propagating direction. Results showed a rather remarkable angular dependence of T(φ) on the Co content for different wavelengths. It was attributed the behavior of this to be dependent on the so-called magnonphoton interaction.

  • NMR is an experiment in which the resonance frequencies of nuclear magnetic systems are investigated. NMR always employs some form of magnetic field (usually a strong externally applied field B0) NMR is a form of both absorption and emission spectroscopy, in which resonant radiation is absorbed by an ensemble of nuclei in a sample, a process causing detectable emissions via a magnetically induced electromotive force.

  • Chapter 13 - Nuclear magnetic resonance spectroscopy. In this chapter, students will be able to understand: Use the chemical shifts, splitting patterns, and integrations shown in a proton NMR spectrum to propose structures for possible compounds; use the number of peaks and their chemical shifts in a 13C NMR spectrum to determine the number of types of carbon atoms in the compound and what functional groups they might represent;...

  • Magnetic nanoparticles absorb energy from external alternating magnetic field to create a nanosized heating source. Specific loss power (SLP) is affected strongly by several magnetic parameters of material and viscosity of nanofluid. In this study, the specific loss power as dependent on saturation magnetization was calculated for hard ferrite CoFe2O4 (K = 290 kJ/m3 ) and soft ferrite MnFe2O4 (K = 3 kJ/m3 ) with two values of viscosity in biological range 1-2 mPas.

  • Today, research and technology play a decisive role for the European food sector for the development of new products as well as for improved safety measures. In July 2000, DG RTD requested a study on potential future European research priorities in food technology and food safety from the Institute for Prospective Technological Studies (IPTS), Joint Research Centre. The study design comprised the involvement of external expertise from industry as well as from academia: The results of the study were derived from two experts workshops held in Sevilla at the IPTS in December 2000 and May 2001.
