摘要

A series ofpolycrystalline garnets Y3-aRaFe5-6MebO12 with different saturation magnetization has been prepared by conventional ceramic techniques. Measurements were made on both the iron-rich and the yttrium-rich sides of stoichiometry samples. We studied the effect of small deviation (the deviation value less than 0.15) from stoichiometry on the essential properties of polycrystalline garnets, and analyzed why the changing trend of the dielectric loss tangent on the yttrium-rich side was so different from that on the iron-rich side. The results indicated that for small deviation from stoichiometry of garnets, dielectric loss tangent and remanence ratio are the most sensitive parameters, while dielectric constant is the most insensitive parameter.
