摘要：

The magnetic properties of CeCu2Si2 have been investigated by 63Cu nuclear magnetic resonance (NMR). A spin-density-wave (SDW)-like ordering has been found below 0.6 K for superconducting CeCu2.02Si2 with Tc = 0.72 K by applying the external magnetic field. This type of magnetic ordering has not been observed for non-superconducting CeCu1.9Si2 with a spin-glass transition at Tg = 2.5 K, indicating a strong correlation with the superconductivity.
