摘要: Abstract Mn 3 TeO 6 exhibits a corundum-related A structure and complex magnetic involving two orbits for the atoms [Ivanov et al., 2011 [3] ]. 3− x Cd ( =0, 1, 1.5, 2) ceramics were synthesized by solid state reaction investigated using X-ray powder diffraction, electron microscopy, calorimetric measurements. 2+ replaces cations without greatly affecting of compound. The found to be randomly distributed over -site. Magnetization measurements indicated that samples order antiferromagnetically at low temperature with transition decreases increasing doping. nuclear one specially prepared 114 containing sample: 1.5 , was studied neutron diffraction range 2–295 K. in an incommensurate helical structure, very similar However, lower extension ordered confined 240(10) A.
