Temperature dependence of the magnetic susceptibility $\chi$($T$) is studied in compounds of GdCr$_3$(BO$_3$)$_4$ and ErCr$_3$(BO$_3$)$_4$ by the Faradey method in the wide temperature range (293–1200 K). The dependences $\chi^{-1}$($T$) for all crystals show the nonlinear anomalies caused by structural transitions in the crystals. The $\chi^{-1}$($T$) dependences for paramagnetic phase follow the linear Curie–Weiss law. The Curie’s temperature and values of magnetic moments corresponding to the chemical formula of the crystals are found.

Key words: exchange interaction, paramagnetic temperature, magnetic susceptibility, magnetic moment, law of Curie–Weiss, the rare earth borates.
