This review is on composites with ferromagnetic or ferrimagnetic oxides and ferroelectrics. Systems studied so far include samples with spinel ferrites, hexagonal ferrites or lanthanum manganites for the ferromagnetic phase and barium titanate,...

al. 2013.[13] As discussed in Section I C, the magnetic orders in h-RFeO3 are essentially 120-degree an- tiferromagnetic. Among the four possible magnetic structures, the DM interaction coefficient 22 Di,j is non-zero only for Γ2 and Γ3. The alignment between neighboring FeO layers ...
Hexagonal crystals obtained from this system are characteristically black with highly reflecting natural faces and easy, almost perfect basal cleavage. Crystals up to 1/2 in. long and 1/8 in. thick have been grown. Ferrimagnetic resonance linewidth measurements made on single-crystal disks of (Zn...
Center: the ferrimagnetic spin orientation of the crystal sites for nickel ferrite. Right: the anti‐ ferromagnetic structure for the zinc ferrite. There are A–O–B interactions between the cation on A site and the cations on B sites, and an B–O–B interaction between the cations on the...

Plots of log(σT) versus 103/T are almost linear and have shown a transition near the Curie temperature. The activation energy in the ferromagnetic region is in general less than that in the paramagnetic region. An attempt is made to explain the conduction mechanism in Li–Ge ferrites....
These materials only perform well as an inductor below the frequency where ferromagnetic resonance occurs. Above this cut-off frequency, a coil will have a highly resistive character and the Q-factor of the LC filter circuit will be limited an thus, also the impedance. A better result could ...
(AA interaction) or B-sites (BB interaction). The ions between tetrahedron and octahedron sites are coupled in an antiferromagnetic way, forcing the ions within the tetrahedron or octahedron sites to align in a ferromagnetic way. The total magnetism is caused by the unbalanced magnetic moment ...
Nanoferrites are ceramic powders exhibiting strong ferrimagnetic properties owing to iron oxides being their core component (Rana et al. 2015). The ferrites are classified based on their crystalline structure; (a) hexagonal (MFe12O19), (b) garnet (M3Fe5O12), and (c) spinel (MFe2O4), ...
