Summary on Grant Application Form |
We propose to produce model materials to study fundamental problems in co-operative magnetism using two different synthetic strategies. One line of attack is to prepare extend ionic compounds which happen to have the desired lattice of magnetic atoms; alternatively, we may build the magnetic from molecular units, directing the architecture through the bonding directionality of these units.In both cases the target lattices have a low dimensional and/or frustrated topology, and are designed to probe recent developments in fundamental magnetism that suggest that such materials may have novel magnetic ground states and excitations, and in particular spin fluid character. We also propose to prepare high-spin nanaoscale metallic clusters and study the relaxation of their magnetisation; this is of considerable fundamental interest as an example of a macroscopic process that may be controlled by the quantum mechanical tunnelling; it may also have practical significance as the basis for a molecular magnetic memory device.All of this work requires time-and frequency dependent magnetic susceptibility measurements, so we request an upgrade to existing dc SQUID magnetometer apparatus to allow ac measurements to be performed, and propose to support open access to this equipment, strengthening our informal magnetic characterisation service.
