概要
- 論文の詳細を見る
An inelastic neutron scattering experiment has been performed on a new heavy-fermion compound, YbAgGe, for a polycrystalline sample at zero magnetic field. A quasielastic scattering and a crystal field excitation at 12meV are observed. Both are broadened due to the Kondo effect with an intrinsic width of 0.9 meV at 1.5K, which increases to about 3meV at 300 K. The temperature dependence follows Г_0 + A√<T> typically observed in Kondo systems. Crystal field parameters are also deduced. To explain the result that only one excitation is observed at 12 meV, the B_<22> term is assumed as the main component.
