DESCRIPTION:Prof. S. Blundell\, University of Oxford\nMagnetic materials c
 an be constructed using molecular components to build up novel and unusual
  architectures. This approach provides an exciting opportunity for explori
 ng the physics of magnetism. Gaining control of the building blocks of mag
 netic materials and thereby achieving particular characteristics will make
  possible the design and growth of bespoke magnetic devices. While progres
 s in the synthesis of molecular materials\, and especially coordination po
 lymers\, represents a significant step towards this goal\, the ability to 
 tune the magnetic interactions within a particular framework remains in it
 s infancy but promising advances are being made\, including the production
  of single molecule magnets and a variety of extended structures.  We have
  recently found a chemical method which achieves dimensionality selection 
 via preferential inhibition of the magnetic exchange in an S = 1/2 antifer
 romagnet along one crystal direction\, switching the system from being qua
 si-two- to quasi-one dimensional while effectively maintaining the nearest
 -neighbour coupling strength.  We have also demonstrated that single molec
 ule magnets can be used to store quantum information and have devised a st
 rategy for extending the spin coherence time by chemical adjustment.  The 
 experimental techniques used in this work include ESR\, muSR and high magn
 etic fields.
