Bader Argonne National Laboratory, 9700 South Cass Avenue, Argonne, Illinois 60439, USA (Received 25 February 2004; published 12 July 2004) We introduce nuclear resonant magnetometry as a means to record the magnetization curve of isotopically enhanced regions of a sample. It is based on nuclear resonant scattering with circularly polarized synchrotron radiation and the use of a nuclear resonant reference sample. We apply this approach to study the interlayer coupling in Fe/Cr(100) multilayers and to obtain a layer-specific magnetization curve. Our measurements provide experimental evidence for the existence of a nontrivial interlayer-coupling angle in Fe/Cr/Fe. ©2004 The American Physical Society URL: http://link.aps.org/abstract/PRL/v93/e037201 doi: 10.1103/PhysRevLett.93.037201 PACS: 75.60.Ej, 75.25.+z, 75.70.-i, 76.80.+y Additional Information View ISI's Web of Science data for this article: [ Source Abstract | Related Articles ] ------------------------------------------------------------------------ Full Text: [ PDF (205 kB) GZipped PS Order Document ] ------------------------------------------------------------------------ References Citation links [e.g., Phys.

[ISI] # One could determine the sign of the hyperfine field by observing whether the hyperfine splitting increases or decreases on application of a large external field. This approach, however, cannot be used for magnetization measurements since the sign information should also be accessible in the presence of small external fields where the sample is not necessarily in saturation. # We follow the convention of J.

However, due to the predominant contribution of the core region in our spectra, we are not sensitive enough to the interface to allow for such a detailed hyperfine field modeling. We opted to use only one interface component since this gave already exceptionally good fit results. # T. S. Toellner et al., Phys. Rev. Lett. 74, 3475 (1995 ). [ISI] # V. M. Uzdin et al., Phys. Rev.
