6 p, 2.3 MB Zero-field routing of spin waves in a multiferroic heterostructure / Zhu, Weijia (Aalto University School of Science. Department of Applied Physics) ; Qin, Huajun (Aalto University School of Science. Department of Applied Physics) ; Flajšman, Lukáš (Aalto University School of Science. Department of Applied Physics) ; Taniyama, Tomoyasu (Nagoya University. Department of Physics) ; Van Dijken, Sebastiaan (Aalto University School of Science. Department of Applied Physics)
We report zero-field routing of spin waves in a multiferroic heterostructure comprising a ferromagnetic Fe film and a ferroelectric BaTiO3 substrate with fully correlated strain-coupled domains. In the Fe film, a regular alternation of magnetic anisotropy produces a back-and-forth rotation of uniform magnetization in zero magnetic field. [...]

Departament de Física) ; Navau Ros, Carles (Universitat Autònoma de Barcelona. Departament de Física) ; Sánchez Moreno, Álvaro (Universitat Autònoma de Barcelona. Departament de Física)
Cloaking a three-dimensional object in free space from electromagnetic waves has recently become a theoretical possibility, although practical implementations can only be made in reduced schemes. If static fields are involved, requirements are less restrictive and some practical realizations have been possible. [...]

Departament de Física) ; Chen, Du-Xing (Universitat Autònoma de Barcelona. Departament de Física)
Important modifications on the magnetization loops of the superconductor have been observed in superconductor-ferromagnet hybrids due to the effects of the ferromagnetic components, which can be used for tuning the superconductor critical-current density Jc to desirable values. [...]

5 p, 1.2 MB Controlling vortex chirality and polarity by geometry in magnetic nanodots / Agramunt Puig, Sebastià (Universitat Autònoma de Barcelona.

Departament de Física) ; Sánchez Moreno, Álvaro (Universitat Autònoma de Barcelona. Departament de Física)
The independent control of both vortex chirality and polarity is a significant challenge in magnetic devices based on nano-sized magnetic vortex structures. By micromagnetic simulations here, we show that in soft ferromagnetic nanodots with an adequate modulated thickness, the desired combination of chirality and polarity can be achieved just by changing the direction of the in-plane applied magnetic field.

163 p, 10.1 MB Magnetically induced forces during LISA Pathfinder in-flight operations / López Zaragoza, Juan Pedro ; Nofrarias, Miquel, dir. ; Mompart Penina, Jordi, dir.
Les ones gravitatòries van ser predites per Albert Einstein l'any 1915 dintre del marc de la teoria de la Relativitat General. Segons aquesta teoria, la qual representa la vigent comprensió de la interacció gravitatòria, moviments violents en sistemes de grans quantitats de massa generen pertorbacions que es propaguen en l'espai i el temps, transportant amb elles energia del sistema originari.
