Abstract

ACrO2 compounds have been shown to exhibit a 2D character. LiCrO2 orders 3D at TN = 62 K; possible magnetic structures consistent with neutron powder diffraction measurements are discussed. The 2D ordering in this compound is shown by the diffraction patterns to persist up to 100 K. The temperature dependence of the diffuse intensity of NaCrO2 and KCrO2 indicates a Néel temperature for 3D ordering of 45 and 26 K, respectively; but no sharp peaks consequent upon this ordering are visible in diffraction patterns taken at temperatures down to 2 K.

    The variables that affect the resultant magnetism include crystal symmetry, site symmetry, principal quantum number and spin quantum states of the magnetic ions. Ordered rock salt structure with heavy element transition metals is an interesting class of compounds for this purpose [3–7]. While they offer various triangular and tetrahedral sub-structures of magnetic ions, they bring more diverse oxidation states (especially≥+5 that are rarely seen in 3d elements) and enable systematic alteration of the magnetic properties as a function of spin multiplicity.
