A spectral line inversion code, Very Fast Inversion of the Stokes Vector (VFISV), has been used since May 2010 to infer solar atmospheric parameters from spectropolarimetric observations taken by Helioseismic and Magnetic Imager (HMI) aboard Solar Dynamics Observatory (SDO). The magnetic filling factor, fraction surface with a resolution element occupied field, is set have constant value one in...

We propose a novel type of spin wave computing device, based on bilayer structure that includes “bias layer” made from hard magnetic material and “propagation with low damping, for example, yttrium garnet or permalloy. The bias layer maintains stable pre-recorded magnetization pattern, which generates field desired spatial dependence, in turn sets the equilibrium inside propagation layer. When ...

background: magnetic nanoparticles in a variable magnetic field are able to produce heat. this heat (42-45°c) has more selective effect on fast dividing cancer cells than normal tissues. methods: in this work magnetite nanoparticles have been prepared via co-precipitation and phase identification was performed by powder x-ray diffraction (xrd). magnetic parameters of the prepared nanoparticles ...

The existence and uniqueness of a vector scalar potential representation with the Lorenz gauge (Schelkunoff potential) is proven for any vector field from H(curl). This representation holds for electric and magnetic fields in the case of a piecewise smooth conductivity, permittivity and permeability, for any frequency. A regularized formulation for the magnetic field is obtained for the case wh...

We employ high-spatial resolution spectropolarimetric observations from the Solar Optical Telescope on-board the Hinode spacecraft to investigate the fine structure of the penumbral magnetic fields. The Stokes vector of two neutral iron lines at 630 nm is inverted at every spatial pixel to retrieve the depth-dependence of the magnetic field vector, line-of-sight velocity and thermodynamic param...
