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, 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, 371.3 KB Simultaneous in-plane and out-of-plane exchange bias using a single antiferromagnetic layer resolved by x-ray magnetic circular dichroism / Nogués, Josep (Institut Català de Nanociència i Nanotecnologia) ; Stepanow, S. (Centre d'Investigació en Nanociència i Nanotecnologia) ; Sort Viñas, Jordi (Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas (Spain). Departamento de Energía) ; Dieny, B. (Universitat Autònoma de Barcelona. Departament de Física) ; Nolting, F. (Paul Scherrer Institut (Suïssa)) ; Gambardella, Pietro (Centre d'Investigació en Nanociència i Nanotecnologia) ; Institució Catalana de Recerca i Estudis Avançats ; American Physical Society
We present a study of exchange bias in ferromagnet/antiferromagnet/ferromagnet (FM/AFM/FM) trilayers, with in-plane and out-plane easy axes. Using element-specific x-ray magnetic circular dichroism, we demonstrate that simultaneous in-plane and out-of-plane exchange bias can be induced using a single antiferromagnet and zero field cooling, whereas field cooling only induces exchange bias to the layer with easy axis parallel to the cooling field.
