4 p, 160.5 KB Compatibility of cast search with axionlike interpretation of PVLAS results / Massó i Soler, Eduard, 1954- (Universitat Autònoma de Barcelona. Departament de Física) ; Redondo Martín, Javier (Universitat Autònoma de Barcelona. Departament de Física) ; American Physical Society
The PVLAS Collaboration has results that may be interpreted in terms of a light axionlike particle, while the CAST Collaboration has not found any signal of such particles. We propose a particle physics model with paraphotons and with a low energy scale in which this apparent inconsistency is circumvented.

4 p, 263.2 KB Shell-driven magnetic stability in core-shell nanoparticles / Nogués, Josep (Universitat Autònoma de Barcelona. Departament de Física) ; Skumryev, Vassil (Institució Catalana de Recerca i Estudis Avançats) ; Sort Viñas, Jordi (Institució Catalana de Recerca i Estudis Avançats) ; Stoyanov, S. (University of Delaware. Department of Physics and Astronomy) ; Givord, D. (Centre National de la Recherche Scientifique (França)) ; American Physical Society
The magnetic properties of ferromagnetic-antiferromagnetic Co-CoO core-shell nanoparticles are investigated as a function of the in-plane coverage density from 3. 5% to 15%. The superparamagnetic blocking temperature, the coercivity, and the bias field radically increase with increasing coverage. [...]
