A temperature dependence of the magnetic susceptibility [χ(T)] of rare-earth borates RAl3(BO3)4 (R = Tb, Er, or Ho) is measured by the Faraday method at temperatures in the interval 20–850°С. Nonlinear anomalies caused by structural transitions are observed in the dependences χ–1(T). It is established that the dependences χ–1(T) for each phase obey the linear Curie–Weiss law. The Curie temperatures and the magnetic moments corresponding to the chemical formula of the compounds have been found.
