Abstract
We report magnetic-form-factor measurements for Ir in the cubic antiferromagnet Ir ( K). Even though the Ir ions lie on an fcc lattice and are surrounded by octahedra of Cl, the magnetization density deviates strongly from the cubic symmetry that the charge density shows. This unusual asymmetry is dramatically magnified by the large amount of covalent bonding of the single magnetic hole to the complex.
