Abstract

ESR measurements have been performed in double chain system NH₄CuCl₃ at room temperature under magnetic field up to 1T and at frequency 9.47 GHz. It is reported that the line width ΔH_pp shows anisotropy when the magnetic field direction is varied with respect to a-axis, while it is isotropic with respect to the b-axis. The values of ΔH_pp are very small compared with the sweep width of the measurements. These facts indicate that NH₄CuCl₃ undergoes weak broadening caused by antisymmetric exchange interaction. It is also considered that the broadening is due to Dzyaloshinsky-Moriya interaction.
