抄録

The preparation of fine particles of SrO.6Fe₂O₃ with single phase has been realized by controlling the chemical coprecipitation and heat treatment . A solution containing Fe³⁺ and Sr²⁺ in the ratio 8.0 was poured into a solution of NaOH (pH=13.0). The precipitated products were boiled for 2hs and they were carefully washed and dried. The obtained powder was heated at 900°C for 2hs in air, and resulted in Sr-M single phase. The maximum values of magnetic properties are σ_s=87.0×10^-6 wb-m/kg, H_cJ=501.3 kA/m, average anisotropy filed H_Aave=945.4 kA/m, and T_c=462°C.
