Fe/MgO-based magnetic tunnel junctions are among the most promising candidates for spintronic devices due to their high thermal stability and high tunneling magnetoresistance. Despite its apparent simplicity, the nature of the interactions between the Fe and MgO layers leads to complex finite-size effects and temperature-dependent magnetic properties which must be carefully controlled for practical applications.

We report characterization and magnetic studies of mixtures of micrometer-size ribbons of Mn acetate and micrometer-size particles of YBaCuO superconductor. Extremely narrow zero-field spin-tunneling resonance has been observed in the mixtures, pointing to the absence of the inhomogeneous dipolar broadening. [...]

19 p, 11.4 MB On-Surface Engineering of a Magnetic Organometallic Nanowire / Ormaza, Maider (Université de Strasbourg) ; Robles, Roberto (Institut Català de Nanociència i Nanotecnologia) ; Bachellier, Nicolas (Université de Strasbourg) ; Abufager, Paula (Institut Català de Nanociència i Nanotecnologia) ; Lorente Palacios, Nicolás (Institut Català de Nanociència i Nanotecnologia) ; Limot, Laurent (Université de Strasbourg)
The manipulation of the molecular spin state by atom doping is an attractive strategy to confer desirable magnetic properties to molecules. Here, we present the formation of novel magnetic metallocenes by following this approach. [...]

The creation of molecule-like structures in which magnetic atoms interact controllably is full of potential for the study of complex or strongly correlated systems. Here, we create spin chains in which a strongly correlated Kondo state emerges from magnetic coupling of transition-metal atoms. [...]

4 p, 673.6 KB Resonant interband tunneling spin filter / Ting, David Z. -Y. (California Institute of Technology. Jet Propulsion Laboratory) ; Cartoixà Soler, Xavier (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica) ; American Physical Society
We propose an InAs/GaSb/AlSb-based asymmetric resonant interband tunnelingdiode as a spin filter. The interband design exploits large valence band spin-orbit interaction to provide strong spin selectivity, without suffering from fast hole spin relaxation. [...]

We propose a mechanism for achieving bidirectional spin pumping in conventional nonmagnetic semiconductorresonant tunnelingheterostructures under zero magnetic field. The device is designed specifically to take advantage of the special spin configuration described by the Rashba effect in asymmetric quantum wells. [...]
