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. [...]

(Kavli Institute at Cornell for Nanoscale Science) ; Rivadulla, Francisco (Universidade de Santiago de Compostela. Departamento de Química Física)
We present a detailed analysis of the temperature dependence of the thermal conductivity of a ferroelectric PbTiO3 thin film deposited in a composition-spread geometry enabling a continuous range of compositions from ∼25% titanium deficient to ∼20% titanium rich to be studied. [...]

4 p, 497.0 KB Magnetic domain and domain-wall imaging of submicron Co dots by probing the magnetostrictive response using atomic force microscopy / Wittborn, J. (Kungl. Tekniska högskolan. Department of Materials Science) ; Rao, K. V. (Kungl. Tekniska högskolan. Department of Materials Science) ; Nogués, Josep (Universitat Autònoma de Barcelona. Departament de Física) ; Schuller, Ivan K. (University of California, San Diego. Department of Physics) ; American Physical Society
An approach to image the domains and domain walls of small ferromagnetic entities using atomic force microscopy(AFM), with a nonmagnetic AFM probe, has been developed. Exciting the sample in an external acmagnetic field, the distribution of magnetostrictive response at the surface is detected. [...]

4 p, 232.0 KB Size effects on exchange bias in sub-100 nm ferromagnetic-antiferromagnetic dots deposited on prepatterned substrates / Baltz, Vincent (SPINTEC (Spin Electronics Research)) ; Sort Viñas, Jordi (SPINTEC (Spin Electronics Research)) ; Rodmacq, B. (SPINTEC (Spin Electronics Research)) ; Dieny, B. (SPINTEC (Spin Electronics Research)) ; Landis, S. (Commissariat à l'Énergie Atomique et aux Énergies Alternatives (França)) ; American Physical Society
Exchange bias effects have been investigated in ferromagnetic (FM)-antiferromagnetic (AFM) square dots, with lateral sizes of 90 nm, sputtered on a prepatterned Si substrate. The magnetic behavior of the dots has been compared with that of a continuous FM-AFM bilayer with the same composition. [...]
