La substituted polycrystalline Y3-xLaxFe5O12 (x = 0.0 - 0.5) garnets were manufactured by ceramic method and the structure and magnetic properties of the garnets were studied by X-ray diffractometry, magnetometry, ferromagnetic resonance and permittivity and permeability measurement. Saturation magnetization and Curie temperature of the garnets increase slightly with increasing La content. Resonance linewidth decreases with increasing La concentration x. Complex permittivity and permeability of the garnets are reported.
