Mass Spectrometry Techniques and Applications

We have observed implanted Fe ions to be nonmagnetic in the group VIIb hosts Tc and Re, by applying the in-beam perturbed angular $\ensuremath{\gamma}$-ray distribution method. This result is in agreement with local spin density calculations for Fe in Tc using both supercell and single impurity approaches. The results are of key importance for a reasonable and consistent understanding of the basic, general features of local magnetic moment formation on Fe ions in transition metal hosts.
