Neutron diffraction study of TbFe2Si2 single crystal

Abstract Here, we present results of the neutron diffraction studies on single crystal of the tetragonal intermetallic compound TbFe 2 Si 2 . We have succeeded to grow a high-quality single crystal of TbFe 2 Si 2 . Bulk studies confirmed strong magnetocrystalline anisotropy of this crystal, with the crystallographic c -axis as an easy axis of magnetization. The neutron diffraction experiment has revealed a complex antiferromagnetic ground-state structure with two propagation vectors, namely k 1 =(0.323, 0, 0.152) and k 2 =(0, 0, 0.53). Magnetic phase diagram of TbFe 2 Si 2 is also presented.
