“…In ABO 3 type proper multiferrioc structures, the A‐site sublattice is responsible for ferroelectric and B‐site sublattice is responsible for ferromagnetic properties. The decrease in T N value with increasing Ca 2+ doping at A‐site is a direct consequence of the decreasing average ionic radius 〈 r A 〉 of the A‐site cation 38, 39. The bond strength in BFO always depends upon Fe–O–Fe bond angle ( ϕ ), which is proportional to cos ϕ and this cosine angle is proportional to the Neel temperature 40, 41.…”

The present work reports the analysis of temperature‐dependent electrical and conductivity studies on Ca2+ doped BiFeO3 multiferroic ceramics in the temperature range of 300–600 K. The effect of Ca2+ doping on the impedance and modulus behavior of BiFeO3 lattice is discussed. The observed changes as a function of increasing Ca2+ concentration have been explained using the change in crystal unit cell. It is also shown that the microstructure changes significantly as a function of Ca2+ concentration. The grain and grain boundary effects in determining the impedance behavior is also reported in the paper.

“…BiMnO 3 exhibits ferroelectric as well as ferromagnetic properties and hence can be used as a good multiferroic material [10,11]. The Bi doped manganites have been shown to be prospective materials for multiferroic and bolometric applications [12][13][14][15]. Bi 0.5 Sr 0.5 MnO 3 has been shown to be a promising candidate for use as a cathode material in solid oxide fuel cells because of its high electrochemical performance [16].…”
