The electron paramagnetic resonance (EPR) spectra were observed for ferric borate isostructural crystals MBO(3): Fe(3+) (M = Ga, In, Lu, Sc). The experimental dependences of the spin-Hamiltonian axial parameters of the second-order D(S) and fourth-order (a-F)(cS) versus total pair spin S are presented. The contributions arising from the distortion of the parent crystal lattice MBO3 under magnetic dilution are estimated. The microscopic derived expressions for the "single-ion" contribution to the anisotropy are also presented. The present experimental data enable estimation of the "single- ion" exchange contribution for FeBO(3), MnCO(3), and alpha-Fe(2)O(3) crystals at T= 0 K. The quantitative estimations for EPR are in satisfactory agreement among themselves and with the experimental data.
