摘要：

Transmission of mm-wave radiation through single crystals of CsCuCl3 was measured in magnetic fields up to 10 T. The q=0 spinwave gap was found by zero-field resonance in the temperature range between T=2K and TN=10.5K. For T=2K we got for the gap 98.5 GHz. The experimental field dependence of the resonance modes in configurations with the field parallel and perpendicular to the c-axis can be well explained by a simple model of three spinchains whose spins lie in the a,b-plane with 120° angle between one another at zero field. In the framework of our model we can determine the product of interchain exchange field and planar anisotropy field HexHd very accurately. © 1990.
