The “in-plane” angular spin distribution in layered systems as obtained by 57Fe Mössbauer spectroscopy

Research output: Contribution to journalArticlepeer-review

A practical approach for in-plane angular spin distributions in layered systems, as obtained by Mössbauer spectroscopy, is discussed. The line intensity ratio R23 of a Mössbauer pattern is expressed versus particular distribution parameters in unidirectional, step-shaped and ellipse-type models. The distribution parameters are deduced from experimental spectra taken by rotating the sample in its own plane. Three-dimensional spin distributions with small out-of-plane components can be analysed using the same method. The procedure is exemplified on four samples containing metallic nano-particles. The in-plane angular magnetic moment distributions derived with this method are compared with the results from bulk vector vibrating sample magnetometry in order to prove the accuracy of the described technique.
