In this work, we report the synthesis, structure and magnetic properties of SrFe11T1O19 (T = Ga,Cr,In,Al) hexaferrite powders obtained by Pechini method. For all the samples, formation of the M-type structure was verified, together with a significant grain size coarsening, from 100 to 3000 nm. The magnetic properties include remarkable coercivity values of… CONTINUE READING
