“…Large variations in the saturation magnetization, however, could be due to the presence of impurity phases in some prepared samples. Further, modifications of the properties of Y-type hexaferrites by substitutions for Fe 3+ ions were also reported [12,35,49,51,94,[96][97][98][99][100][101][102][103]. However, research work devoted to the effects of such substitutions in Y-type hexaferrites is relatively limited.…”

Abstract. The present study is concerned with the fabrication and characterization of Me2Y substituted hexaferrites, Ba2Me2Fe12-xTxO22 (Me = Co 2+ , Mg 2+ , and Cr 2+ , and T = Fe 3+ , and Ga 3+ ). The samples were prepared by the conventional ball milling technique and sintering at 1200° C. The effect of the choices of Me and T ions on the structural and magnetic properties of the hexaferrites were investigated. XRD patterns, magnetic parameters, and Mössbauer spectra of the Co2Y were consistent with a single phase Y-type hexaferrite. However, the CoCr-Y sample was found to be dominated by the Y-type hexaferrite, and M-type and BaCrO4 minority phases were observed in the XRD pattern of the sample. The small increase in saturation magnetization from about 34 emu/g up to 37.5 emu/g was therefore attributed to the development of the M-type phase. On the other hand,

“…Thus, it is desirable to develop a low-temperature burned (below 950 °C) magnetic material having a higher quality factor than nonmagnetic materials at 200-300 MHz for use in the manufacture multilayer high frequency chip inductor. Ferrites with a hexagonal structure show higher dispersion of frequencies than NiCuZn ferrites used in microwave applications [7,8]. Among these ferrites BaFe12O19 and SrFe12O19 -M-type ferrites having good magnetic properties such as permeability and quality factor above 200 MHz [9].…”

In the review examined the possibility of using LTCC-technology for obtaining hexaferrites as reaction additives glasses Bi2O3-B2O3-SiO2-ZnO (BBSZ) and BaCu (B2O5) (BCB) to reduce the sintering temperature. It is shown that compatibility between hexaferrites with the addition BBSZ, BCB and silver paste, which is a key requirement in the manufacturing process LTCC-components. Considered the possibility of co-sintering of ferrites and dielectric tape composites. It was established that for the realization of defectfree LTCC-composite need to control the shrinkage of the two tapes. In this connection becomes an important concept of zero shrinkage and limiting sintering.

“…Magneto‐plumbite ferrites with a hexagonal structure exhibit a higher dispersion frequency than nickel ferrites because of the magnetic anisotropy of the magneto‐plumbite . Among those ferrites, the Co 2 Y ferrites, 2(BaO)·2(CoO)·6(Fe 2 O 3 ), have good magnetic properties (such as permeability and quality factor) above 200 MHz . The Zn substitution can promote M s , and hence increase the permeability of Co 2 Y ferrites .…”

The Bi 2 O 3 -B 2 O 3 -ZnO-SiO 2 (BB35SZ) glass effects on the sintering behavior and magnetic properties of Bi-Zn co-doped Co 2 Y ferrites were investigated in developing low-temperature-fired ferrites. The results indicate that BB35SZ glass can be used as a sintering aid to reduce the densification temperature of Co 2 Y ferrites from 1300°C to 900°C. The 2(Ba 0.9 Bi 0.1 O)·2(Zn 0.4 Co 0.4-Cu 0.2 O)·6(Fe 1.97 Zn 0.03 O 3 ) ferrite with 4 wt% BB35SZ glass can be densified below 900°C, exhibiting an initial permeability of 3.4 and quality factor of 55. This process provides a promising candidate for multilayer chip magnetic devices for microwave applications.*
