Abstract
We have measured the 27Al and 157Gd nuclear magnetic relaxation times and their rf power dependence in GdAl2 at 4.2 K. The relaxation times at the two peaks in the 27Al spectrum are different, confirming that the main contribution to the NMR signals comes from domain walls in the first peak (49 MHz) and from domains in the second peak (61 MHz).
