In the present contribution we have studied the dielectric properties of two-phase sodium borosilicate glasses doped by iron oxide and of porous media based on them. The temperature dependences of dielectric permittivity and conductivity for all samples have been obtained, and the impedance spectroscopy analysis for porous magnetic glasses has been done. The obtained data allow us to estimate the values of activation energies for porous samples.
