A group of researchers, led by UPC university, has discovered that atoms react differently depending on the characteristics of the support that is used. Part of this study, which has been published today in Science, was performed at the NAPP endstation of CIRCE beamline of ALBA Synchrotron.
Manuel Vázquez, from the Institute of Materials Science of Madrid (CSIC), is the 1.000th researcher using ALBA’s facility. He and his team will analyse magnetic nanowires at CIRCE beamline.
Laura Martin, Matteo Monti, Jose F. Marco and Juan de la Figuera (from the IQFR-CSIC, Instituto de Química Física "Rocasolano") investigated the (100) surface of a Fe3O4 (Magnetite) single crystal using the CIRCE-PEEM endstation in different imaging modes.
X-RAY LINEAR DICHROISM, PERPENDICULAR MAGNETIZATION AND IN-SITU MAGNETIC FIELDS. Using a ferrimagnetic Fe3O4 natural single crystal, first images with X-ray magnetic linear dichroism contrast (XMLD) have been obtained in Photo Emission Electron Microscopy (PEEM) at CIRCE. Although the XMLD effect is typically much weaker in ferromagnetic materials than the more commonly used circular dichroic effect (XMCD), it is a unique tool when it comes to the investigation of antiferromagnetic systems without net magnetic moment.
David Pesquera, Blai Casals, Gervasi Herranz and Josep Fontcuberta from the Institut de Ciència de Materials de Barcelona (ICMAB-CSIC) have used new in-situ electrical poling capabilities at the PEEM microscope to image magnetic switching in a ferromagnetic La2/3Sr1/3MnO3 (LSMO) thin film.
