摘要：

Spin dynamics of an incommensurate spin-density wave (SDW) in small gamma-Fe precipitates in Cu was studied by neutron inelastic scattering. Strong spin fluctuations were observed around the broad SDW satellite peak positions even above the Neel temperature. This is not the magnon excitation because no such inelastic scattering is observed at the well defined SDW satellite peak positions for large gamma-FeCo precipitates. Similarities to the SDW clusters in CuMn spin-glass alloys are discussed.
