English Abstract
Neutron powder diffraction has been performed on Li2TbF6, K2TbF6 and Rb2TbF6 fluoroterbates. Incommensurate long-range magnetic order is observed below TN=2.02, 1.60 and 2.07 K. The square-modulating of the magnetic ...Read more >
Neutron powder diffraction has been performed on Li2TbF6, K2TbF6 and Rb2TbF6 fluoroterbates. Incommensurate long-range magnetic order is observed below TN=2.02, 1.60 and 2.07 K. The square-modulating of the magnetic structures can be correlated with the geometric frustration induced by the pseudo-hexagonal packing of the [TbF6]2− chains in these hexafluorides. This frustration and the magnetic interactions are discussed on the basis of experimental data and topological considerations...Read less <
