Dielectric behaviour and magnetoelectric effect in copper–cobalt ferrite+barium lead titanate composites

Studies on structural, electrical and magnetic properties of y(Ni0.5Zn0.3Co0.2Fe2O4)+(1−y)(BaTiO3) composites

“…The resistivity plots clearly show two regions of conductivity. The first region observed at lower temperatures may be due to impurities and is attributed to the ordered ferroelectric phase and the second region that occurs at higher temperatures which is due to polaron hopping may be attributed to disordered paraelectric state [14]. The activation energy was calculated by using the relation…”

Enhanced magnetic behavior, exchange bias effect, and dielectric property of BiFeO3 incorporated in (BiFeO3)0.50 (Co0.4Zn0.4Cu0.2 Fe2O4)0.5 nanocomposite

“…But recent theoretical breakthrough in understanding the co-existence of magnetic and dielectric orderings in some materials initiated the researchers in the field of MFs. 6,7 Cross-coupling between magnetic and electric order parameters in these materials, termed as magnetoelectric coupling, is of special interest. Various materials exhibit the MF property at room temperature (RT) and in this family BiFeO 3 (BFO) is a very well known candidate, which can be considered as a most widely studied MF.…”

In situ formation of sol-gel derived PbTiO3/NiFe2O4 biphase thin film

“…The magnetoelectric (ME) composites can provide both inductance and capacitance. They are used as sensors, wave guides, etc [4]. Moreover, they have the ME effect [2].…”

“…The ME composites are usually compounded into bulks or films using ferromagnetic phase and ferroelectric phase which are prepared separately by ceramic sintering [1][2][3][4][5][6] or sol-gel method [7][8][9][10]. Compared with the conventional method, in situ combination of the ME composites makes the two phases contact on a molecule scale level, leading to high ME coefficient [2,5].…”
