Abstract	The influence of the physicochemical state of the particle surface on the interparticle magnetic interaction in a closepacked system of singledomain microcrystals of highly anisotropic hexaferrite BaFe12O19 has been studied. The efficiency of the used technique of treatment of the particle surface with acid and alkali solutions has been determined from the data on the Fe3+ ion concentration in the solution and on the change in the elemental composition in the nearsurface layer. It has been shown that, when the etched layer thickness is 2.5c (c is the lattice parameter of ferrite), the parameter of the resulting interparticle interaction changes qualitatively and quantitatively. The technologically accessible technique used allows the attenuation of the interparticle magnetic interaction in a system of closepacked particles by several times.
