5-We M~ssbauer and magnetic measurements of BiPbSr2FeO6 calcinated in air (sample 1)or in N2 gas (sample II) were made. Sample I is a weak-ferromagnet with T~=240 K, The temperature dependence of the magnetization shows an anomaly at 90 K. A ta~e effect of the magnetic field cooling is observed. Fe
