Magnetic excitations in the double-perovskite La2CuIrO6.
We propose to study magnetic excitations in the double perovskite 3d-5d system La2CuIrO6 using IN4 time-of-flight spectrometer. Our specific aim is to establish the presence of spin gap and to estimate the magnon band width on a 5 g powder sample of this material. The crystal structure is determined by two interpenetrating fcc lattices of octahedra centred around copper and iridium ions. Previous characterisation reveals AFM phase transition at 74 K followed by FM transition at 55 K, resulting in a complex non-collinear low-temperature magnetic structure.
