Search for new iron single-molecule magnets
The synthesis, X-ray structure, and magnetic properties of a trinuclear iron complex with the formulation [Fe3O2Cl2(4,7-Mephen)6](BF4)3 (complex 1) are reported. DC magnetic susceptibility measurements show the Fe atoms are antiferromagnetically coupled, yielding an S /5/2 ground state. An investigation as to whether complex 1 exhibits the properties associated with singlemolecule magnetism was...
متن کاملVariable Field Bending Magnets for Recirculating Linacs
A lattice of single aperture superconducting variable field bending magnets is proposed as a cheap and practical way to recirculate the beams in recirculating linear accelerators. It is shown that the VFBM's can be configured to provide strong focusing in both transverse planes for the full range of beam momenta transported by the lattice.
متن کاملSingle-molecule magnets: Iron lines up.
T he bottom-up synthesis of magnetic materials is a key aim of research in molecular magnetism. The goal is not to compete with bulk magnets, such as those decorating the fridge door at home or operating valves in your car, whose magnetism depends on the collective contributions of neighbouring magnetic atoms arranged with long-range order. Instead, molecules that are intrinsically magnetic — s...
متن کاملCluster-Assembled Iron-Platinum Nanocomposite Permanent Magnets
Exchange-spring nanocomposite permanent magnets have received a great deal of attention for their potential for improved the energy products. Predicted results, however, has been elusive. Optimal properties rely on a uniformly fine nanostructure. Particularly, the soft magnetic phase must be below approximately 10 nm to ensure complete exchange coupling. Inert gas condensation (IGC) is an ideal...
متن کاملAdaptive Field-oriented Control of Synchronous Motors with Damping Windings
Two different nonlinear dynamic control algorithms are presented for synchronous motors with damping windings: (i) an adaptive speed-sensorless controller for rotor position tracking in the presence of unknown constant load torque, on the basis of rotor angle, stator and field windings currents measurements; (ii) an adaptive control law for rotor speed tracking in the presence of uncertain cons...
