Structural and electrical studies of Ba5RTi3V7O30 (R=Ho, Gd, La) compounds

Structural, electrical, and multiferroic characteristics of lead-free multiferroic: Bi(Co0.5Ti0.5)O3–BiFeO3 solid solution

“… 58 The AC-conductivity of BCTF80/20 has been calculated in accordance with the impedance data. 59 In accordance, a suitable formalism specifies the occurrence of a hopping mechanism to the electrical conduction in the compound that has been examined with the following Jonscher's power equation: 60–62 σ ac ( ω ) = σ α + Aω η where the symbol σ α represents a frequency independent part, which provides the value of dc-conductivity, η is the frequency exponent term having value between zero and one, and the symbol A is a constant (temperature-dependent) that has polarizability strength.…”

Modulating the magnetic properties of BiFeO3 by addition of Ba5TbTi3V7O30

“…BFO has a rhombohedrally distorted perovskite structure with the space group R3c [7,8]. There are several reports on the modification of magnetic properties (Neel temperature, T N ) of BFO by addition of niobate ferroelectrics [9,10]. It has also been observed that the magnetic ordering param-eters in BFO can be improved by employing the solid solution technique with other ferroelectric compounds [11].…”
