Neutron diffraction studies of magnetic structure of TbAg2Si2
Source abstract
Abstract
Abstract Powder neutron diffraction measurements have been performed on TbAg2Si2 at low temperatures. The compound crystallize in the tetragonal ThCr2Si2-type crystal structure (space group I4/mmm). Below TN=18 K TbAg2Si2 orders antiferromagnetically with a sine-wave modulated structure characterized by the propagation vector k =(1,0.3249(5),0) . The Tb magnetic moments, equal 8.36(22) μB, are in the basal plane as expected from the positive sign of the B20 parameter of the crystal electric field Hamiltonian.
