Аннотация: Magnetic properties of GdFe3(BO3)(4) single crystals were investigated by Fe-57-Mossbauer spectroscopy and static magnetic measurements. In the ground state, the GdFe3(BO3)(4) crystal is an easy-axis compensated antiferromagnet, but the easy axis of iron moments does not coincide with the crystal C-3 axis, deviating from it by about 20 degrees. The spontaneous and field-induced spin reorientation effects were observed and studied in detail. The specific directions of iron magnetic moments were determined for different temperatures and applied fields. Large values of the angle between the Fe3+ magnetic moments and the C-3 axis in the easy-axis phase and between Fe3+ moments and the a(2) axis in the easy-plane phase reveal the tilted antiferromagnetic structure.
