Depth profile of uncompensated spins in an exchange bias system Roy, S. Fitzsimmons, M. R. Park, S. Dorn, M. Petracic, Oleg Roshchin, Igor V. Li, Zhi-Pan Batlle Gelabert, Xavier Morales, R. Misra, A.

Materials Propietats magnètiques Cristal·lografia Magnetic properties and materials Crystallography We have used the unique spatial sensitivity of polarized neutron and soft x-ray beams in reflection geometry to measure the depth dependence of magnetization across the interface between a ferromagnet and an antiferromagnet. The net uncompensated magnetization near the interface responds to applied field, while uncompensated spins in the antiferromagnet bulk are pinned, thus providing a means to establish exchange bias. 2010-07-05T09:49:19Z 2010-07-05T09:49:19Z 2005 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0031-9007 https://hdl.handle.net/2445/13281 527535 eng Reproducció digital del document proporcionada per PROLA i http://dx.doi.org/10.1103/PhysRevLett.95.047201 Physical Review Letters, 2005, vol. 95, núm. 4,p. 047201-1-047201-4 http://dx.doi.org/10.1103/PhysRevLett.95.047201 (c) American Physical Society, 2005 info:eu-repo/semantics/openAccess 4 p. application/pdf American Physical Society Articles publicats en revistes (Física de la Matèria Condensada)
