Cover Story: Octahedral nickel(II) complexes are the simplest systems that exhibit zero-field splitting. A distorted octahedral nickel(II) complex was synthesized using a tetradentate ligand. Each of the three methods (angular overlap model analysis based on diffuse reflection spectra, density functional theory calculations based on crystal structure, and simultaneous analysis of magnetic susceptibility and magnetization) showed a positive zero-field splitting parameter. The exact algebraic expression for the angular dependence of magnetization has been derived, which allows us to simulate magnetization anisotropy. The simulation shows that the complex is easily magnetized in the xy-plane direction. View this paper
