Compositional dependence of the magnetic state of Co3-xZnxTeO6 solid solutions

[摘要] The magnetic properties of phase-pure solid solutions of Co3-xZnxTeO6 are investigated using magnetometry (single crystals) and neutron diffraction (polycrystalline powders), and compared to results of detailed crystallographic studies. There are five unique Co sites in Co3TeO6, including a tetrahedrally coordinated Co-2 site which Zn preferentially occupies. The magnetic interaction is found to monotonically decrease as the Co-2-O bond length decreases with increasing Zn content. The results suggest a modification of the magnetic structure in the samples containing Zn. (C) 2021 The Author(s). Published by Elsevier B.V.
