“…Some of the well-known multiferroics are BiFeO 3 [3], BiMnO 3 [4], boracite family compounds [5], BaMF 4 type of materials [6], rare earth molybdates [7], rare earth-based manganites [8], etc. As it is possible to vary the magnetization of these materials with varying electric field/stress, these materials may be exploited for variety of applications including high-sensitivity ac magnetic field sensors, electrically tuneable microwave devices such as filters, oscillators and phase shifters.Out of all the multiferroic oxides known today, BiFeO 3 (BFO) has drawn a lot of attention due to interesting properties exhibited by the material.…”

With a view to understand the influence of rare earth ion doping on the structural, magnetic and dielectric properties of bismuth ferrite, a series of samples were prepared by the solidstate reaction method. After characterizing the samples with XRD and SEM studies, the magnetic and dielectric measurements were carried out. It is interesting to note that the two impurity phases, viz., orthorhombic Bi 2 Fe 4 O 9 and cubic Bi 25 FeO 40 observed in undoped bismuth ferrite are found to vanish with rare earth doping. Further, the remnant magnetization (M r ) values are found to increase with increasing ionic radii of dopant rare earth ion. Interestingly, among all the samples, La doped BiFeO 3 sample is exhibiting negative magnetization at low temperatures. The dielectric constant is found to exhibit two transitions above room temperature. Efforts have been made to explain the observed structural, magnetic and dielectric behaviours of the materials.

“…1 illustrates possible configurations of spins in two magnetization states, corresponding to points a and b. This switching reflects a converse magnetoelectric coupling coefficient of ␣ = 0 ͑dM/ dE͒ = 1.6ϫ 10 −7 s m −1 which is comparable to the largest direct ME coupling with sharp domain switching, ⌬P / ⌬H ϳ 10 −9 s m −1 , 3,18 and the recently reported room temperature value of ␣ ϳ 2 ϫ 10 −8 s m −1 for a La 0.67 Sr 0.33 MnO 3 / BaTiO 3 film heterostructure. 4 Additionally, this result compares favorably with other laminated heterostructures with direct ME coupling without magnetization switching, such as Pb͑Zr, Ti͒O 3 /terfenol-D, ϳ10 −8 s m −1 .…”

A demonstration of magnetization reversal via the application of electric field across a multiferroic heterostructure, consisting of a FeCoV ribbon bonded to a lead magnesium niobate-lead titanate crystal, is presented. The magnetization switching occurs by an abrupt change in magnetization near ferromagnetic coercivity, coinciding with an electrical field-induced magnetic anisotropy field. Experiments reveal a converse magnetoelectric coupling of ␣ = 0 ͑dM/ dE͒ = 1.6ϫ 10 −7 s m −1 upon magnetization reversal in the strain-mediated heterostructure. The frequency dependence of magnetization switching is presented and explained within the framework of a relaxation model for the multiferroic heterostructure.

“…[1][2][3][4] Unfortunately, candidate multiferroic materials are very rare due to the mutual exclusivity of the origins of FM and electric polarization, in which FM needs transition metals with unpaired 3d electrons and unfilled 3d orbital, while FE polarization needs transition metals with filled 3d orbital. Furthermore, the available multiferroic candidates, such as BiFeO 3 , 5-9 BiMnO 3 , [10][11][12] and DyFeO 3 , 13 all have serious drawbacks, i.e., electric leakage or low temperature for appearance of multiferroic properties.…”

Single phase Bi2FeMnO6 was synthesized on Si substrates by an electrospray method. Three peaks were observed in the temperature dependence of magnetization curve, which is attributed to the inhomogeneous distribution of Fe3+ and Mn3+. The observed magnetic peaks at 150 K, 260 K, and 440 K correspond to orderings of the ferrimagnetic Fe–O–Mn, and antiferromagnetic Mn–O–Mn and Fe–O–Fe, respectively. Heat capacity measurements were carried out to confirm these magnetic transitions. The Debye temperature of Bi2FeMnO6 is 339 K, calculated from Debye–Einstein fitting.
