The drop of coercivity, while preserving the saturation magnetic polarisation J_{S} of substituted M-type Ba hexaferrites with composition BaFe_{12-2x}(Me_{1}Me_{2})_{x}O_{19}, was studied. Divalent Me_{1}=Ni, Zn, Sn and tetravalent Me_{2}=Ru, Sn ionic combinations were used in various compounds. Mössbauer spectroscopy was used to reveal sites of replacement of the Fe^{3+} ions by Ru^{4+} and Sn^{4+}. The Ni^{2+}, Zn^{2+} and Sn^{2+} occupation sites were identified as well. Strong drop of coercivity difference Δ H_{c}(x) near x=0.1 and slight decrease of Δ H_{c}(x) close to x=0.3 was obtained for suitable coupling of Me_{1}^{2+ }and Me_{2}^{4+} ions.
