Crystal structure of TbMn6Sn6 (IMAGE) DOE/Ames National Laboratory Caption Graphical representation of the crystal structure of the TbMn6Sn6 material at the atomic level. Here the Mn and Tb atoms appear as blue and green balls, respectively. Lines connecting near neighbors reveal the Mn Kagome and Tb triangular lattices. The magnetism present on this element is represented by arrows located on each individual atom. The magnetic interactions acting within and in-between the different atomic planes are displayed by the square brackets and labeled by the letter “J” with the subscript M and T used to denote the Mn or Tb elements they link.
