- Abstract:
- We investigate the electric fielddistribution around ferromagneticnanoparticles(NPs)inferrofluids underthe infuenceof external magneticfield．Specifically，magneticcore(cobalt)coated with a metallic lay．er(gold)isconsidered，which incorporated optically actively component with magneticNPs．Due to the magnetic response，the core／shellNPswill alignalong the direction of external magnetic field，thus forminga linear NPschain in the system．With the solution of Laplace’S equations，electric fields inside andoutside the NPschain are explored as a function of the incident wavelength operatingonthe basis of mutualinteraction a— mongthe polarizedparticles．Analytical study showsthat themaximummagnitudeof the electric filed is closely related to the resonant incident wavelength．the metallic shell thicknessandthe inter．particle distance．
