Self-Assembled BaTiO3-MnZnFe2O4Nanocomposite Films

“…Another reason is that the MZF may not be fully decomposed from BTO matrix even after annealing at 1020 • C for one hour. The latter can be confirmed by the measured saturated magnetization, 330 emu/cc, lower than the bulk value of 380 emu/cc [22]. Figure 4 shows the change of polarization as a function of the applied electrical field of the annealed BTO-MZF at a constant frequency of 1 kHz.…”

A review on MnZn ferrites: Synthesis, characterization and applications

“…MnZn ferrites are of great interest due to their wide range of applications such as hyperthermia applications [141], power applications [109][110][111], magnetic fluid [145], high frequency power supply, memory storage devices, TV sets, biomedicines [146], magnetic resonance, catalysis etc. There is a continuous progress in the size and shape control of MnZn ferrites and also on the morphological and magnetic properties of MnZn ferrites by using different methods [147] of synthesis like sol-gel method [96][97][98], co-precipitation method [85,[102][103][104][105][106][107][108][109]143], conventional ceramic technique [110,111], hydrothermal method [112][113][114][148][149][150], citrate precursor method [115], solid state reaction method [118], autocombustion method [119,151], microemulsion method [120]. The effect of doping on the structural and magnetic properties of pure MnZn ferrites is also taken into account.…”

Electrical and magnetic properties of Co substituted MnZnFe2O4

“…In preventing radio frequency interference, small size particles can possess some useful properties compared to the bulk size. These particles have also improved catalytic, dielectric, and magnetic properties as they possess high resistivity and negligible eddy current losses 1–4. Materials containing these particles can be half‐metallic as the bulk materials such as Fe 3 O 4 (magnetic oxide of iron) or insulating (most spinel ferrites), transparent conductors 5 as with Cd 2 SnO 4 , ferrimagnetic (most spinel ferrites), heavy‐fermion compounds 6 as with LiV 2 O 4 or antiferromagnetic ZnFe 2 O 4 .…”
