Abstract
Using the thermal cycling method, the nuclear spin lattice relaxation of186ReFe and182TaFe has been measured in polarizing fields of 0.1 to 1.2 T. The results for the relaxation constants in the high-field limit are 87(2) and 470(10) ms K, respectively. The relaxation rates are about a factor of three larger than expected from ab initio calculations. It is proposed to interprete this discrepancy as proof for a significant spin wave contribution to the relaxation.
