“…Then, the magnetization decreased with increasing the substitution rate from x = 0.5 up to 1.5. This result is consistent with the fact that M-type ferrite showed similar Zn-Ti substitution dependence of spontaneous magnetization 37) , where the magnetization began to decrease above a certain Zn-Ti substitution rate.

“…Concerning the cation distribution in the W-type structure, we assume that the Zn 2+ ions prefer the 4e and 4fIV sites and that Ti 4+ ions prefer the 12k sites. In the case of the (ZnTi) substituted M-type ferrite 37) , Zn 2+ ions tend to enter the tetrahedral 4fIV sites in the S block. Also, Ti 4+ ions tend to enter the octahedral 4fVI (the R block) sites and the 12k (the S and R blocks border) sites.…”

We report the synthesis of (Zn 2+ Ti 4+ ) substituted hexagonal ferrites, BaZn2(Zn0.5Ti0.5)xFe16-xO27 (W-type) and Ba2Zn2(Zn0.5Ti0.5)xFe12-xO22 (Y-type), and the relationship between their composition and magnetic properties. Substituted W-type ferrite was synthesized in the region of 0.0 ≤ x ≤ 1.5. A decrease in the Curie temperature of the W-type phase indicated that the exchange interactions between the Fe 3+ ions weakened due to the substitution of Zn 2+ and Ti 4+ ions. Spontaneous magnetization (σS) at x = 0.5 was similar to that at x = 0.0. This reflects the equal distribution of nonmagnetic Zn 2+ and Ti 4+ ions to spin down sites and spin up sites, respectively. At x > 0.5, σS decreased clearly, which was possibly caused by a deviation from the collinear arrangement. Substituted Y-type ferrite was also obtained up to x = 0.5. The Y-type phase is more unstable than the W-type phase with respect to this substitution rate.

Ferrimagnets having low RF loss are used in passive microwave components such as isolators, circulators, phase shifters, and miniature antennas operating in a wide range of frequencies (1-100 GHz) and as magnetic recording media owing to their novel physical properties. Frequency tuning of these components has so far been obtained by external magnetic fields provided by a permanent magnet or by passing current through coils. However, for high frequency operation the permanent part of magnetic bias should be as high as possible, which requires large permanent magnets resulting in relatively large size and high cost microwave passive components. A promising approach to circumvent this problem is to use hexaferrites, such as BaFe 12 O 19 and SrFe 12 O 19 , which have high effective internal magnetic anisotropy that also contributes to the permanent bias.Such a self-biased material remains magnetized even after removing the external applied magnetic field, and thus, may not even require an external permanent i

“…superexchange interaction is disrupted and weakened as a consequence of the atomic distances between the magnetic moment producing ions anticipated to change [10,11,13] , it can be clearly seen from FTIR results that all organic materials were burnt out. XRD and XPS results show that the dopant elements substituted crystal lattice parameters as required without generating undesirable phases or evaporation.…”

“…The intrinsic magnetic properties of the barium hexaferrite can be changed by partial substitutions for Ba or Fe sites [6][7][8][9][10][11][12]. Previous works have shown that the magnetic properties of barium hexaferrite could be changed by substituting Ba 2+ with rare earth ions [10,[13][14][15].…”
