DESCRIPTION:Metal-organic frameworks are a diverse family of materials but
 \, as recognised in the recent Nobel Prize\, offer striking opportunities 
 to design in space. In this seminar I will discuss recent work in my group
  in harnessing this to realise new magnetic states\, challenging to realis
 e in classical\, dense inorganic magnetic materials. \n\nI will discuss ou
 r work on two-dimensional van der Waals metal organic magnets (MCl2L)\, wh
 ere we controlled structure and interactions to realise a range of differe
 nt properties\, from routes towards the Haldane S = 2 quantum chain[1] to 
 controllable non-collinear ferromagnetism.[2]\n\nIn addition to providing 
 control over interactions in existing structure types\, MOFs also exhibit 
 a diversity of topologies\, and hence magnetic phases\, not previously dis
 covered. I will discuss our computational work showing that there are high
  symmetry topologies that would produce new spin liquid states\, which cou
 ld be realised in MOFs[3] together with our on-going experimental efforts 
 to use neutron scattering to uncover new magnetic states in MOF glasses[4]
  and four dimensional lattices.\n\n[1] J. Pitcairn et al.\, J. Am. Chem. S
