(Wiley-VCH Verlag, 2014)New solid solutions Cu2MnxFe1-xSnS4 were prepared by direct combination of the corresponding elements at 850°C. The crystal structure of Cu2Mn0.4Fe0.6SnS4 was determined by single-crystal X-ray diffraction. This phase is ...
-
(TAYLOR & FRANCIS LTD, 2010)Arrays of Co nanowires with different lengths and diameters have been prepared by electrodeposition into nanopores of alumina and polycarbonate membranes. The dependence of the coercivity and remanence of the arrays as ...
-
(Royal Society Chemistry, 2017)Asymmetric macrocyclic complexes of the type [M2LCl2]center dot xH(2)O have been obtained and intercalated using the potassium precursor phase K0.4Mn0.8PS3 center dot H2O (M: Zn-II or Cu-II; LH2: macrocyclic ligand derived ...
-
(The European Physical Journal D - Atomic, Molecular, Optical and Plasma Physics, 2007-07)We report a comparative study of the magnetic properties of free-standing PdN clusters (2 ≤ N ≤ 21) obtained through two different theoretical approaches that are extensively employed in electronic structure calculations: ...
-
(KYOTO UNIV, RESEARCH INST MATHEMATICAL SCIENCES, 2009-04-24)In previous articles, a magnetic pseudodifferential calculus and a family of C-algebras associated with twisted dynamical systems were introduced and the connections between them have been established. We extend this ...
-
(2008)In this work we report results from continuous-wave (CW) and pulsed electron paramagnetic resonance (EPR) and proton nuclear magnetic resonance (NMR) studies of the vanadium pentoxide xerogel V2O 5:nH2O (n ≈ 1.6). The low ...
-
(TAYLOR & FRANCIS LTD, 2006)This work describes an Electron Paramagnetic Resonance (EPR) and Nuclear Magnetic Resonance (NMR) study of the vanadium pentoxide xerogel V2O5:nH(2)O with n approximate to 1.8 Experiments were performed in the temperature ...
-
(1989)The spin-lattice interaction, which very recent experiments suggest is significant in the layered perovskites, is modeled by adding to the coupling constant of the anisotropic Heisenberg antiferromagnet a linear dependence ...
-
(2013)Although barotropic matter does not constitute a realistic model for magnetic stars, it would be interesting to con rm a recent conjecture that states that magnetized stars with a barotropic equation of state would ...

(Universidad de Chile, 2006)Este trabajo da cuenta de la medición de magnetorresistencia longitudinal (campo eléctrico paralelo al campo magnético) y la magnetorresistencia en la configuración MacDonal (campo eléctrico perpendicular al campo ...
-
(Universidad de Chile, 2005)En este trabajo, informo las primeras medidas de magnetorresistencia donde la señal puede ser atribuida inequívocamente al scattering electrón-superficie, realizadas en 4 películas de oro evaporadas sobre un substrato ...
-
(IOP, 2020)A detailed analytic and numerical analysis of the interaction between two bubble skyrmions has been carried out. The results from the micromagnetic calculations show that when the skyrmions are in the same plane, the ...
-
(American Physical Society, 2020)Magnonic excitations in the two-dimensional (2D) van der Waals (vdW) ferromagnet chromium triiodide (CrI3) are studied. We find that bulk magnons exhibit a nontrivial topological band structure without the need for ...
-
(American Physical Society, 2017)© 2017 American Physical Society.We show that the interaction between the spin-polarized current and the magnetization dynamics can be used to implement black-hole and white-hole horizons for magnons - the quanta of ...
-
(1978)Glucokinase is a monomeric protein under native and denaturating conditions yet presents a sigmoidal saturation function for glucose. These peculiarities suggested the possibility that polymerization occurs under assay ...
-
(AEET. Asociación Española de Ecología Terrestre, 2020)La malaria aviar es una enfermedad causada por parásitos sanguíneos transmitidos por mosquitos. En el hospedador, los parásitos infectan órganos y tejidos causando daño celular, afectando finalmente a la condición física ...

Male and female golden whistlers respond differently to static and dynamic signals of male intruders (OXFORD UNIV PRESS INC, 2008-09)Bird displays vary widely in their sensitivity to changes in signaler condition. Plumage ornaments are generally static and undergo minimal change. Behavioral ornaments, by contrast, are dynamic and may track signaler ...
