Tetragonal, scheelite-type Pb1–3x□xGd2x(MoO4)1–3x(WO4)3x materials (x = 0.0455, 0.0839, 0.1154, 0.1430, 0.1667 and 0.1774, where □ denotes vacancies) synthesized via solid state reaction route were magnetically and electrically examined. The
Until the 1970s, only three basic elements: R, C, and L have been used to construct RLC circuits. These elements are two-ports of zero order (resistances) and of first order (capacitances and inductances). Their presence in electronic circuits causes

Scheelite-type Ca1−xMnxMoO4 (x = 0.0, 0.01, 0.05, 0.10 and 0.15) nanomaterials were successfully synthesized via a combustion route. Dielectric studies showed a weak n-type electrical conductivity characteristic for insulators and low relative perm

The UV–vis–NIR and electrical conductivity σ ( T ) measurements of RE 2 W 2 O 9 (RE = Pr, Sm–Gd) showed the insulating state and the calculated value of the direct allowed energy gap E g > 3.5 eV. Thermoelectric power S ( T ) measurements show

Broadband dielectric spectroscopy and magnetic measurements provide experimental evidence that the CdMoO4:Gd 3+ single crystal is the paramagnet with low relative dielectric permittivity (er � 8), which slightly depends on the temperature and frequ
