Spin-lattice Relaxation Rates of Os and Other 5d Elements in Fe

Abstract

We give final results for the nuclear spin-lattice relaxation (SLR) rates of 5d series elements as dilute impurities in iron using the method of thermal cycling on oriented nuclei. In this report, we emphasise some aspects of the analysis of the relaxation curves, especially for Os and Au impurities. A comparison of the results with theory is given.
