摘要：

The magnetic properties of Kondo compounds CeNiAl4 and CeNi2Al5 (T(N) = 2.6 K) have been investigated using NMR and NOR techniques. In CeNi2Al5, the NQR linewidth of Al-27 broadens from 40 kHz above T(N) to 320 kHz at T = 1.3 K. 1/T1 below T(N) decreases rapidly without divergence at T(N) and seems to be proportional to e(-DELTA/T) in a narrow T-range 1.3-2.3 K. In CeNiAl4, preliminary results of 1/T1 of Al-27 are reported.
