The present paper reports on the specific heat and magnetization of the YFe3(BO3)4 and ErFe3(BO3)4 single crystals. In both compounds, antiferromagnetic order of the iron spins evolves at TN = 38 K. The experimental data suggest that the magnetic moments are in the basal plane of the trigonal crystal for both compounds. In the magnetically ordered state the crystal is subdivided into three types of domains, the magnetic moments of the Fe3+ ions being aligned along the a axis within each domain. For ErFe3(BO3)4, two non-equivalent magnetic positions of the Er3+ ions in each domain are observed.
