An investigation on synthesis and magnetic properties of nanoparticles of Cobalt Ferrite coated with SiO2
SiO2-coated Cobalt Ferrite (CoFe2O4) nanoparticles were obtained by the hydrolysis of tetraethylorthosilicate in the presence of CoFe2O4 nanoparticles in co-precipitation. The effects of SiO2coating on the magnetic properties of CoFe2O4 nanoparticles were investigated. The structural, morphological and magne...

متن کاملEffective field theory approach to light propagation in an external magnetic field
The recent PVLAS experiment observed the rotation of polarization and the ellipticity when a linearly polarized laser beam passes through a transverse magnetic field. The phenomenon cannot be explained in the conventional QED. We attempt to accommodate the result by employing an effective theory for the electromagnetic field alone. No new particles with a mass of order the laser frequency or be...
متن کاملMagnetic-field-driven instability in stratified ferrofluids.
We describe a convective instability of a stratified ferrofluid subject to a magnetic field. The ferrofluid is described as binary mixture featuring two important dimensionless numbers the barometric one B and the magnetic barometric one Bm. At the field strength, where the latter exceeds the former, instability sets in. We discuss the growth rate of linear perturbations and the amplitude of no...
