Electromagnetic properties of a new ferrite-ceramic low-temperature cocalcined (LTCC) composite materials

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

“…The higher values of έ of the nanocomposite may due to the interfacial polarization, as exhibited by other MF composites. 61 In the measured values of dielectric constant of the present nanocomposite sample, we have also observed the presence of the dielectric relaxations with thermally activated features, which was confirmed by the high losses above unity at higher region of temperatures in the lower frequency region. This is quite likely due to the enhanced magnetization in the nanocomposite sample of BFO-CZCF.…”

Microwave-Hydrothermal synthesis of BaTiO3+NiCuZnFe2O4 nanocomposites

“…However, in present composites the large values of ε have been attributed to the fact that ferroelectric grains are surrounded by ferrite grains. This in itself gives interfacial polarization [10]. 9 gives the typical magnetic spectra (initial permeability ( i ) versus frequency) for all the composites under investigation.…”

“…From the survey of literature, it is found that BaTiO 3 + NiCuZn ferrite composites were prepared using sol-gel, auto combustion [9], solid state reaction [10] and oxalate precipitation [11] methods. However, detailed investigation of dielectric properties were not undertaken in any of these studies.…”

Electrical and magnetic properties of NiCuZn–CaCu3Ti4O12 composites doped with Bi2O3

“…Many material systems, such as NiCuZn ferrite-(Ba, Sr)TiO 3 , NiCuZn ferrite-PNNT and NiCuZn ferrite-Pb(Zr, Ti)O 3 have been prepared in the last few years [3][4][5][6][7][8]. CaCu 3 Ti 4 O 12 (CCTO), a typical giant dielectric material, has recently attracted many attentions due to its unusually dielectric properties of high and relatively temperature-independent permittivity value of >10,000 over a wide temperature range ∼100-600 K [9,10].…”
