Â· At the expense of high specific electrical resistivity (Ï >106 OmÂ·sm) ferrites are characterised by low dielectric losses at high frequencies tgÎ´=10-2Ã·10-4).
Â· Dielectric permittivity Îµâ (about 10-15)
Â· Thermal stability in a wide temperature range
Â· The high activity is being determined by the value of minimal bias which is essential for required nominal parameters providing.
Â· Saturation magnetization, M s; 4ÏMs (400-5000 G)
Â· The width of resonance curve 2ÎH is one of the main parameters characterising properties of ferrites applied in high-frequency band. The yttrium-iron monocrystals exhibit the minimal value 2ÎH =0.3-0.5 Oe. The width of resonanse curve of polycrystalline ferrites varies from 30â¦40 to 800-1000 Oe.

Materials on the base of yttrium iron garnetsCHIYUE manufactures ferrites or ceramics on the base of compounds with garnet and spinel structures. Yttrium-iron garnets are applied for production of different high-frequency devices operating in low border of high-frequency band. The great interest to ferrites with garnet structure, particularly, to yttrium garnet is explained by narrow line of ferromagnetic resonance absorption. Such materials are also characterised by small magnetic losses; relatively high magnetization; high thermalstability.Often ions of Cobalt and Rare-earth ions (Dy), (Gd) are introduced to materilas structure in order to improve material characteristics for increasing of ferrite stability to Power.
Materials on the base od compunds with spinel structureFerrite materials on the base of Mg spinel are characterised by small values of coercive field strength and also by low magnetic and dielectric losses that allows to use them in fields far from resonance area. cocernintg devices operating nerby resonance area the great is interest is attracted to materials on the base of Ni spinel. Such ferrites are characterised by a wide range of magnetization and high thermal stability. Ferrites on the base of Li spinel can be used in discrete phase shifters. Small values of coercive field strength and thermal stability in operating temperature range and a wide range of saturation magnetization values are characteristic for such materials.
By associating the ferrites with a dielectric material, it is possible to develop a wide choice of composites for miniaturizing isolator/circulator designs.
