We report the shock‐wave synthesis at a yield ≳80% by volume of the single copper layer thalliumsuperconductor of composition Tl2Ba2CuO6. The as‐synthesized material displays zero resistance near 55 K and a diamagnetic onset to bulk superconductivity at 70 K. [...]

4 p, 332.2 KB Direct measurements of magnetostrictive process in amorphous wires using scanning tunneling microscopy / Costa, J. L. (Kungl. Tekniska högskolan. Department of Condensed Matter Physics) ; Nogués i Sanmiquel, Josep (The Royal Institute of Technology. Department of Condensed Matter Physics) ; Rao, K. V. (Kungl. Tekniska högskolan. Department of Condensed Matter Physics) ; American Physical Society
We demonstrate a versatile capability to measure directly the magnetostrictive properties through the magnetization process on a nanometric scale using a modified scanning tunneling microscope. Single 10 mm long, 125 μm diam amorphouswires of both positive and negative magnetostriction have been studied and the data are compared with the hysteretic loops determined by both ac and SQUID magnetic measurements.

4 p, 346.4 KB Large exchange bias and its connection to interface structure in FeF2–Fe bilayers / Nogués i Sanmiquel, Josep (University of California–San Diego. Physics Department) ; Lederman, D. (University of California, San Diego. Department of Physics) ; Morán, T. J. (University of California, San Diego. Department of Physics) ; Schuller, Ivan K. (University of California, San Diego. Department of Physics) ; Rao, K. V. (Kungl. Tekniska högskolan. Department of Condensed Matter Physics) ; American Physical Society
Large exchange bias effects (ΔE 1. 1 erg/cm2) were observed in antiferromagnetic (FeF2)–ferromagnetic (Fe) bilayers grown on MgO. The FeF2 grows along the spin‐compensated (110) direction. The FeF2–Fe interface roughness was characterized using specular and diffuse x‐ray diffraction and atomic force microscopy. [...]

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 i Sanmiquel, 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. [...]

Arrays of ferromagnetic circular dots (with diameters ranging from 225 to 420 nm) have been prepared at the surface of atomically ordered paramagnetic Fe60Al40 (at. %) sheets by means of ion irradiation through prelithographed poly(methyl methacrylate) (PMMA) masks. [...]
