Magnetic Structures of Y₆(Fe₁₋ₓMnₓ)₂₃ Compounds
Neutron diffraction studies of eleven compounds across the compositional range of the Y//6(Fe//1// minus //xMn//x)//2//3 system reveal the presence of substantial preferential atomic ordering of Fe and Mn atoms on the four transition metal crystallographic sites. Throughout the entire compositional range, Mn atoms prefer to occupy the f//2 site and Fe atoms the f//1 site. Neutron diffraction profile refinements reveal no long range magnetic ordering occurring in the compositional range from x equals 0. 4 to 0. 75 as a consequence of the sharply reduced exchange interactions in the ternary compounds. In the Mn-rich ternaries the Fe atoms have no spontaneous moments and the Mn moments are decreased dramatically from Y//6Mn//2//3.
