Аннотация: The thermodynamic properties of alumoborate TmAl3(BO3)4 single crystal are studied experimentally and theoretically. A theoretical analysis based on the crystal field model makes it possible to interpret all measured parameters. The crystal field parameters are determined. The temperature (3–300 K) and field (up to 9 T) dependences of magnetization are described. The field and temperature dependences of multipole moments of the Tm3+ ion in TmAl3(BO3)4 make it possible to describe magnetostriction and low-temperature anomalies in thermal expansion.

Аннотация: The colossal (more than threefold) decrease in the dielectric constant E in the easy-plane SmFe3(BO3)(4) ferroborate in a magnetic field of similar to 5 kOe applied in the basal ab plane of the crystal has been found. A close relation of this effect to anomalies in the field dependence of the electric polarization has been established. It has been shown that this magnetodielectric effect is due to the contribution to E from the electric susceptibility, which is related to the rotation of spins in the ab plane, arises in the region of the antiferromagnetic ordering T T (N) and electric polarization in the magnetic field has been proposed, taking into account the additional anisotropy in the basal plane induced by the magnetoelastic stresses.

Аннотация: The method to investigate "single-ion" exchange anisotropy (as predicted by the pair model) is treated by exploration of several isostructural diamagnetic crystals containing magnetic impurities. 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.
