Sr2CuWO6 is a double perovskite at the border between two and three dimensional magnetism, with a square lattice of S=1⁄2 Cu(II) ions. This proposal aims to use inelastic neutron scattering to investigate the spin wave excitations (below T_N) of the system, and to find out how the excitations evolve as a function of temperature across T_N. Results will be compared against electronic structure calculations for the exchange interactions.
