dc.description.abstract | A series of Co2+-doped and Gd3+-co-doped calcium molybdato-tungstates, i.e., Ca13xyCoy
xGd2x(MoO4)13x(WO4)3x (CCGMWO), where 0 < x 0.2, y = 0.02 and represents vacancy, were
successfully synthesized by high-temperature solid-state reaction method. XRD studies and diffuse
reflectance UV–vis spectral analysis confirmed the formation of single, tetragonal scheelite-type
phases with space group I41/a and a direct optical band gap above 3.5 eV. Magnetic and electrical
measurements showed insulating behavior with n-type residual electrical conductivity, an almost
perfect paramagnetic state with weak short-range ferromagnetic interactions, as well as an increase
of spin contribution to the magnetic moment and an increase in the power factor with increasing
gadolinium ions in the sample. Broadband dielectric spectroscopy measurements and dielectric
analysis in the frequency representation showed a relatively high value of dielectric permittivity at
low frequencies, characteristic of a space charge polarization and small values of both permittivity
and loss tangent at higher frequencies. | pl_PL |
