Numerical Modelling of Disordered Magnetic Systems: La2-xSrxCoO4
  Magnetic properties of La2-xSrxCoO4 have been modelled using McPhase for different doping levels x. Footprints of different interactions, such as local single ion anisotropy and variations in the exchange interactions have been identified in the profile of the diffuse elastic neutron scattering cross section. The role of quantum fluctuations in the formation of the hourglass spectrum is discussed.
