High-permeability and high-Curie temperature NiCuZn ferrite

Effect of sintering temperature on microstructure and electrical properties of Sr1−x(Na0.5Bi0.5) x Bi2Nb2O9 solid solutions

“…10). Su et al [66] determined that the behavior of Curie temperature can be related to microstructure, lattice defect, porosity, grain size, etc. Generally, the free energy of the ferroelectric phase increases and Curie temperature decreases with the increase of internal stress which can be relieved by pores [67].…”

Electromagnetic properties of samarium-substituted NiCuZn ferrite prepared by auto-combustion method

“…NiCuZn ferrite is one of the most important magnetic materials for multilayer chip inductor (MLCI) applications due to their high electrical resistivity, low sintering temperature and high permeability [1][2][3][4][5]. MLCIs are applied in large amounts in various electronic circuits and they have greatly benefited the miniaturization of many latest electronic products, including mobile phones, notebook computers and video cameras.…”

“…Analytical grade nickel nitrate [Ni(NO 3 ) 2 Á 6H 2 O], zinc nitrate [Zn(NO 3 ) 2 Á 6H 2 O], copper nitrate [Cu(NO 3 ) 2 Á 3H 2 O], iron nitrate [Fe(NO 3 ) 3 Á 9H 2 O], citric acid [C 6 H 8 O 7 Á H 2 O] and samarium oxide [Sm 2 O 3 ] were used to prepare Ni 0.25 Cu 0.2 Zn 0.55 Sm x Fe 2Àx O4 ferrite with x ¼ 0.00, 0.025, 0.05 and 0.075 compositions. Metal nitrates and citric acid solutions were prepared using deionized water.…”

Room temperature long range ferromagnetic ordering in Ni0.58Zn0.42Co0.10Cu0.10Fe1.8O4 nano magnetic system

“…The common criteria for every application are the lowest magnetic loss due to which high resistivity is needed for these materials. In this regard Ni-Zn-ferrite is highly suited for their applications as soft magnetic materials because of low coercive field, high saturation magnetization, high Curie temperature, high-resistivity, chemical stability, lower power loss and low-production cost [3,4]. To carefully study and exploit the potential and possibilities associated with nanomaterials, the key point is to create well-defined, mono-disperse structures of predictable size, shape, crystallinity, and morphology through a straightforward synthesis.…”
