Cover Picture: Molecular Spin Clusters: New Synthetic Approaches and Neutron Scattering Studies (ChemPhysChem 9/2003)

Abstract

AbstractThe cover picture shows the principles of inelastic neutron scattering (INS) in magnetic molecular clusters. An incoming monochromatic neutron beam is scattered by a target sample (here a tetranuclear nickel(II) complex) both elastically (no energy transfer) and inelastically (positive or negative energy transfer). Scattered neutrons of varying velocity are then collected in detector banks that span a wide angular range. The interactions between the magnetic moments of the sample and the neutrons that occur during INS allow the investigation of the magnetic properties of the material and the accurate determination of the relevant parameters, including those associated with exchange i..
