| Popis: | SiO 2 powders with magnetic properties have been prepared via the sol–gel method. Morphology of the magnetic powders has been investigated by scanning electron microscope (SEM). The magnetic susceptibility and electric permittivity measurements of the obtained materials have been performed by means of the lumped-capacitance method. The complex magnetic permeability measurements have been performed by means of the inductance method using toroidal-shaped samples. |
