Abstract

NH4CuCl3 has two magnetization plateaus at one-quarter and three-quarters of the saturation magnetization, irrespective of the external field direction. Magnetic excitations in NH4CuCl3 have been investigated by means of neutron inelastic scattering experiments. The constant-Q energy scan profiles were collected in a*-c* plane. Two well-defined magnetic excitations were observed. The dispersion relations along four different directions were determined. Both excitations are found weakly dispersive. The results were compared with those obtained from the ESR measurements.
