摘要：

The inelastic magnetic scattering from a single crystal of Cr0.98Mn0.02 alloy has been studied both below and above the Néel temperature. Measurements at 300 K using the diffraction method have yielded a value for the spin-wave velocity of 1.290.26×107 cm/sec in good agreement with theoretical predictions. At a temperature of 1.16TN inelastic magnetic scattering persists strongly even though there is no ordered or localized moment. This scattering has been interpreted as being due to paramagnonlike excitations, and a line-shape calculation based on this theory fits the experimental results quite well. © 1969 The American Physical Society.
