dc.description.abstractThe measurement of spin waves from magnetic crystals has been a longstanding success story of inelastic neutron scattering. The development of linear spin wave theory [1,2] predates the first neutron scattering measurements and is well developed and suited to the determination of spin waves from magnetic ions with large spins. However to date there has been limited success in applying spin wave theory to lower symmetry crystal structures; such structures are commonly occurring in molecule based magnetic systems whereby the packing of the organic ligands often favours lower symmetry space groups. Further the determination of powder averaged spectra has previously been difficult. Recently spin wave calculation software has become readily available; one such package SpinW [3] readily address the problems of low symmetry and powder averaging. A rotation matrix strategy is implemented so that it is suitable for incommensurate structures. In this contribution we will demonstrate the power of these techniques using data obtained on the cold neutron time-of-flight spectrometer PELICAN for the distorted kagomé lattice Mn3(1,2,4-(O2C)3C6H3)2. [4] Our interest in the distorted kagomé lattice compound stems from the observation of a combination of magnetic ordering and glassy behaviour in a distorted frustrated network. Our inelastic neutron scattering and spin wave theory results allow us to characterise all of the exchange interactions in the distorted lattice and relate these to the degree of frustration in the lattice.en_AU
