    The following article appeared in Journal of Applied Physics 111.2 (2012): 024307 and may be found at http://scitation.aip.org/content/aip/journal/jap/111/2/10.1063/1.3677985Strain-induced self-assembled La0.7Sr0.3MnO 3 nanoislands of lateral size 50-150 nm and height 10-40 nm have been grown on yttria-stabilized zirconia (001)-substrates from ultradiluted chemical solutions based on metal propionates. The nanoislands grow highly relaxed withstanding the epitaxial relation (001)LSMO[110]//(001) Ysz[010] and show bulk-like average magnetic properties in terms of Curie temperature and saturation magnetization. The interplay of the magnetocrystalline and shape anisotropy within the nanoisland ensemble results in an in-plane magnetic anisotropy with a magnetocrystalline constant K 1(150K) = -(5±1) kJ/m3 and in-plane easy axis along the [110] -La0.7Sr0.3MnO3 direction as measured, for the first time, through ferromagnetic resonance experiments. Magnetic force microscopy studies reveal the correlation between nanoisland size and its magnetic domain structure in agreement with micromagnetic simulations. In particular, we have established the required geometric conditions for single domain, multidomain, and vortex configurations.We acknowledge the financial support from MEC (MAT2008-01022, Consolider NANOSELECT and FPU), Comunidad Autónoma de Madrid (CAM S2009/MAT-1467), Generalitat de Catalunya (Catalan Pla de Recerca 2009-SGR- 770 and XaRMAE), and EU (NESPA).

    Dinero como lo singular universal: una lectura del concepto de dinero en Marx desde la Categoría de la Medida de Hegel

    Get PDF
    Se propone una lectura del análisis de la forma de valor de Marx desde el primer tomo de la Wissenschaft der Logik de Hegel. El segundo capítulo de la categoría de la Medida será la figura en la que se identifiquen la forma singular, total y universal del valor de Marx. Frente a las lecturas fisicalistas del Das Kapital, se mostrará el carácter estrictamente relacional tanto de la categoría de la Medida como del concepto de Valor. El artículo termina con la figura de la Wissenschaft der Logik que hace posible comprender el carácter universal singular del concepto de dinero marxiano. Palabras clave: Marx, Hegel, Medida, Valor, Dinero, neutralización, universal-singular. Abstract:A reading of the value form analysis of Marx from the Hegels Wisseschaft der Logik is proposed. The second chapter of the Mass Category will be the figure in which the singular, total and universal value form of Marx is identified. Against the physicalist interpretations of Das Kapital, the strictly relational nature of both, the Mass Category and the Value concept will be here shown. The paper finishes with the figure of the Wissenschaft der Logik that makes possible the understanding of the singular-universal nature of the Marxian concept of money. Keywords: Marx, Hegel, Mass, Value, Money, neutralization, singular-universal nature.</p
