摘要：

Magnetic excitations of. the mixed crystal Cs3Yb1.8Dy0.2Br9 were measured by high-resolution inelastic neutron scattering on the instrument IN5 at the ILL, Grenoble. The YbDyBr93- dimers show magnetic excitations at 0.058 and 0.101 meV with clear-cut Q dependencies. This can be understood in terms of a simple theoretical model in which two Kramer's doublets are coupled by anisotropic exchange.
