Nowdays,  iron  nanoparticles  due  to  their  unique  characteristics  are used  in  all  of  sciences  and  technology.  These  nano  particles  due  to their  electrical, magnetic,  optical  and  catalytic  properties  and  having high  area  and  activity  that  is  promped  by  their  small  size  and most importantly  many  scientists  from  the  entire  world  are  interested  in th...

in this study, a novel magnetic nanocomposite (ba-α-bi2o3-γ-fe2o3) was successfully synthesized through a combination of ultrasound and co-precipitation method under mild conditions. the structure of the synthesized nano-composite as a visible light photocatalyst was investigated by the xrd, tem, hrtem, uv-vis and ft-ir. the hrtem confirmed that the nano-magnetic composites are rods with diamet...

Nano-antennas in functional plasmonic applications require high near-field optical power transmission. In this study, a model is developed to compute the near-field optical power transmission in the vicinity of a nano-antenna. To increase the near-field optical power transmission from a nano-antenna, a tightly focused beam of light is utilized to illuminate a metallic nano-antenna. The modeling...

It is demonstrated analytically that the spectrum of small-amplitude spatially uniform magnetization excitations in an in-plane magnetized magnetic pillar with two ferromagnetic layers coupled by dipole-dipole interaction can be approximately described by the traditional Kittel formula with reduced saturation magnetization and effective anisotropy field. The spectrum consists of a quasi-symmetr...

Spin resolved edge states are ideal candidates for the implementation of dual-rail quantum computation architectures by encoding the qubit in the spin degree of freedom of the co-propagating edge states. An important element for the realization of such architectures is a coherent beam splitter that controllably mixes the two co-propagating spin-resolved edge channels. Coupling of the spin resol...

In recent years magnetic nanoparticles (MNPs) are widely used in different scientific field. In magnetic resonance imaging (MRI), MNPs increase the contrast and quality of the images. In addition, magnetic nanoparticles, as separator, can break up some pathogenesis from human body. On the other hand, under DC magnetic field, MNPs can carry and release drug into the target tissue. In this approa...
