摘要：

Temperature-dependent high-resolution optical spectra of the Er3+ probe ion in DyFe3(BO3)(4) and HoFe3(BO3)(4) are reported. The data provide the temperature of magnetic ordering and direction of the Fe3+ magnetic moments. Both compounds order magnetically at T-N = 39 +/- 1K. The magnetic structure of DyFe3(BO3)(4) is of the easy-axis type, while that of HoFe3(BO3)(4) is of the easy-plane type. The role of anisotropic interactions between the iron and the rare-earth subsystems is discussed. (c) 2007 Elsevier B.V. All rights reserved.
