EMERGENT MAGNETISM AT TRANSITION-METAL-NANOCARBON INTERFACES
Using ALBA's synchrotron light, researchers have shed light on the origin of the magnetism arising at carbon/non-magnetic 3d,5d metal interfaces. These results may allow the manipulation of spin ordering at metallic surfaces using electro-optical signals, with potential applications in computing, sensors, and other multifunctional magnetic devices.

GRAPHENE-BASED SYNTHETIC ANTIFERROMAGNETS AND FERRIMAGNETS
A team of researchers from ALBA and ICN2 have developed novel graphene-based antiferromagnetic multilayer structures featuring robust magnetic properties. These results, published in Nature Communications, demonstrate that single-layer graphene spaced magnetic thin film structures present perpendicular antiferromagnetic coupling together with a number of properties that are well suited for applications.

ELECTRONICALLY CUBIC CONDITIONS IN α-RuCl3, A CANDIDATE MATERIAL FOR THE OBSERVATION OF MAJORANA FERMIONS
Researchers have demonstrated the "electronically cubic conditions" and the Jeff = 1/2 ground state for Ru in α-RuCl3, a pre-requisite for Kitaev Physics and the possibility for studying in this material Majorana fermion excitations. This work has been published as a Physical Review B Rapid communication and editor's suggestion.

ON-SURFACE POLYMERIZATION ONTO A RARE-EARTH SURFACE-ALLOY
A team of researchers from the Centro de Física de Materiales (CSIC-UPV/EHU), Donostia International Physics Center (DIPC), San Sebastián, and ALBA have demonstrated that it is possible to realize atomically-organized organic nanostructures on a magnetic substrate of a reare-earth surface alloy without altering the magnetic properties of the substrate. The results, published in the journal ACS Nano, demonstrate that by clever engineering of the magnetic substrate it is possible to attain on-surface synthesis of tailored organic nanostructures thus opening the possibilities to study and control the magnetic properties of carbon-based magnetic nanostructures such as graphene nanoribbons.

INSTALLATION OF THE NEW SAMPLE TRANSFER SYSTEM
The interstation sample transfer system (SPTR) is an UHV interconnection system built between HECTOR and MARES endstations. It connects the endstations with each other and with a third chamber/system either brought by users or to a (currently under design) satellite surface-preparation chamber for BL29, allowing to transfer a sample mounted on a standard Omicron/Specs type plate between each system in UHV conditions.

DISENTANGLING THE ORIGIN OF MAGNETIC PROXIMITY EFFECTS IN Pt/CoFe2O4
Researchers from ICMAB-CSIC and ALBA have analyzed the microscopic origin of the so-called "magnetic proximity effect" occurring at the interface between a magnetic material (CoFe2O4) and a nonmagnetic metal (Pt), which may induce a magnetic moment in the latter. The results are published in ACS Applied Materials & Interfaces.

FIRST PHD THESIS WITH RESULTS MEASURED AT BOREAS
Eduardo Solano, from the Universitat Autònoma de Barcelona (UAB) and the Institut de Ciència de Materials de Barcelona (ICMAB-CSIC), obtained his PhD degree last November 2013 with a work about the synthesis of nanoparticles and the generation of new nanocomposite superconducting layers. Some of the measurements were acquired at BOREAS beamline in ALBA Synchrotron.

ABSENCE OF MAGNETIC PROXIMITY EFFECTS IN MAGNETORESISTIVE Pt/CoFe2O4 HYBRID INTERFACES
Pure spin currents and spin accumulation and consequently magnetism can be induced in non-magnetic materials just by a flow on a non-spin-polarized charge current (Spin Hall effect). However, magnetism in some non-magnetic materials can also been induced by proximity effect by neighbouring magnetic layers. A group of researchers, led by Josep Fontcuberta from the ICMAB-CSIC, show that in Pt/CoFe2O4 hybrid systems, spin currents are generated in the absence of any proximity-induced magnetic moments in Platinum.
