Nuclear Spin Lattice Relaxation

We have determined the nuclear spin-lattice relaxation (SLR) rates of Ni and Ru as dilute impurities in iron using the method of thermal cycling on oriented nuclei. The samples were prepared by recoil implantation from the heavy ion reactions used to produce the radioactive Ni and Ru isotopes employed in the measurements. In the 3d impurity series, only Sc, Ti, and Cu remain to complete the systematics of the SLR in iron host; in the 4d series, values for Zr and Pd are still missing and the datum for Rh has a large experimental uncertainty. We discuss the comparison with theory and with other experimental results.

Comparison Of The Results

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.

Rare Opportunity

Measurements of iodine nuclear spin lattice relaxation in Rb2PtI6 provide a rare opportunity to directly measure the separate contributions of the ordinary and anharmonic Raman processes. It is shown that for this crystal one may separately determine W1 and W2 and that these rates may be uniquely related to the two Raman processes. The experimental results show that the anharmonic Raman process is dominant but not to the total exclusion of the ordinary Raman process.
