Magnetic structures of the tri-rutiles NiTa 2O 6 and NiSb 2O 6
Abstract
The magnetic structures of the tri-rutiles NiSb 2O 6 and NiTa 2O 6 were determined by neutron powder diffraction. In both cases the magnetic moments are collinear aligned parallel to [1 1 0]. In the tetragonal plane ferromagnetic and antiferromagnetic chains exist, which are perpendicular to each other. But in antimonate these chains run along the [1 0 0]- and [0 1 0]-directions in contrast to [1 1 0] and [1 1¯ 0] for the tantalate. Along the [0 0 1]-direction the orientations are alternating for both compounds, i.e. k z= {1}/{2}.
