dc.description.abstract | Gd3+-doped lead molybdato–tungstates with the chemical formula of
Pb1–3x□xGd2x(MoO4)1–3x(WO4)3x (where x = 0.0455, 0.0839, 0.1430, corresponding to 9.53, 18.32,
33.37 mol% of Gd3+, respectively, as well as □ denotes cationic vacancies) were successfully
synthesized via combustion route. The XRD and SEM results confirmed the formation of single-phase,
tetragonal scheelite-type materials (space group I41/a) with the uniform, spherical and oval grains
ranging from 5 to 20 μm. Individual grains are strongly agglomerated into big clusters with the size
even above 50 μm. The magnetic measurements as well as the Brillouin fitting procedure showed
paramagnetic state with characteristic superparamagnetic-like behaviour and the short-range
ferromagnetic interactions. The electrical and broadband dielectric spectroscopy studies revealed
insulating properties with the residual electrical n-type conduction of 2×10–9 S/m and low energy loss
(tanς ~ 0.01) below 300 K. Dielectric analysis showed that no dipole relaxation processes in the
Gd3+-doped materials were observed. A fit of dielectric loss spectra of Gd3+-doped samples by sum of
the conductivity and the Havriliak–Negami, Cole–Cole, and Cole–Davidson functions confirmed this
effect. | pl_PL |
