Magnetic activity and hot Jupiters of young Suns: the weak-line T Tauri stars V819 Tau and V830 Tau (Oxford University Press, 2015)We report results of a spectropolarimetric and photometric monitoring of the weak-line T Tauri stars (wTTSs) V819 Tau and V830 Tau within the MaTYSSE (Magnetic Topologies of Young Stars and the Survival of close-in giant ...
-
(MDPI, 2017)We study the effect of the degeneracy factor in the energy levels of the well-known Landau problem for a magnetic engine. The scheme of the cycle is composed of two adiabatic processes and two isomagnetic processes, driven ...
-
(ELSEVIER SCIENCE BV, 2005-04-27)The Caleu pluton, which is located in the Coastal Range of central Chile, consists of three N-S elongated lithologic zones which define an across-pluton compositional variation characterized by a westward increase in SiO2 ...
-
(MDPI AG, 2019)The type of metal oxide affects the activity and selectivity of Fe 2 O 3 -SiO 2 -MeO 2 -Pt (Me = Ti, Sn, Ce) catalysts on the hydrogenation of cinnamaldehyde. The double shell structure design is thought to protect the ...
-
(EDP SCIENCES S A, 2008-09)Aims. This paper is the first in a series that aims to understand the long-term evolution of neutron star magnetic fields. Methods. We model the stellar matter as an electrically neutral and lightly-ionized plasma composed ...
-
(Amer Physical Soc, 2020)Vortices are particle-type solutions with topological charges that can steer the dynamics in various physical systems. By the application of electromagnetic fields onto a homeotropic nematic liquid crystal cell, we are ...
-
(Oxford University Press, 2017-01)Magnetic fields significantly influence the evolution of protoplanetary discs and the formation of planets, following the predictions of numerous magnetohydrodynamic (MHD) simulations. However, these predictions are yet ...
-
(MDPI AG, 2019)We studied the performance of classical and quantum magnetic Otto cycle with a working substance composed of a single quantum dot using the Fock-Darwin model with the inclusion of the Zeeman interaction. Modulating an ...

Magnetic polarity zonation within the El Teniente copper–molybdenum porphyry deposit, central Chile (Springer, 2010)El Teniente porphyry copper deposit, the world’s greatest intrusion-related Cu–Mo ore body, is hosted within basaltic–andesitic volcanic and gabbroic rocks (mafic complex). This ore body is strongly affected by multiple ...
-
(Elsevier, 2013)The magnetic properties of [(VO)3(l-PO4)2(2,20-bpy)(l-OH2)]1/3H2O (1) and (VO)2H4P2O9 (2), a tubular and a layered vanadium(IV) phosphates containing triply oxido bridged VIV dimers, are analyzed considering the ...
-
(Walter De Gruyter GMBH, 2020)This study reports the catalytic preparation, characterization, and evaluation of nanoscale coreshell structures with a gamma-Fe2O3 core covered by a SiO(2 )monoshell or by a SiO2@TiO2 multishell as a support for Pt ...
-
(AMER Inst. Physics, 2016)In this work, and by means of micromagnetic simulations, we study the magnetic properties of toroidal nanomagnets. The magnetization ground state for different values of the aspect ratio between the toroidal and polar radii ...
-
(Universidad de Chile, 2018)En este trabajo de tesis se realiza una exploración de magnetometría en laguna Laguna Verde, Chile Chico, Región de Aysén, para encontrar indicadores de la presencia de vetas, estructuras he intrusivos en su cuenca. Esta ...
-
(Universidad de Chile, 2010)En este trabajo se exponen las primeras medidas de magnetorresistencia en películas de oro depositadas sobre mica en la configuración de MacDonald. En esta configuración el campo eléctrico es ortogonal al campo magnético ...

(IEEE, 2015)Magnetostatic modes in ferromagnetic samples have been studied systematically since the 1950s. They are very well characterized and understood in samples with uniform internal magnetic fields. More recently, interest has ...
-
(Springer, 2021)To analyze the process of subduction of the Nazca and South American plates in the area of the Southern Andes, and its relationship with the tectonic and volcanic regime of the place, magnetotelluric measurements were ...
-
(Universidad de Chile, 2015)En esta tesis de doctorado se aborda el estudio de la erosión integrada de cuenca (~140-24000 km^2) en Chile Centro-Sur, particularmente en la Cuenca del Río Biobío, sus subcuencas principales y la zona de ruptura del ...
-
(2011-04)We studied the correlation between the final event magnitude and four parameters obtained from the early portion of P and S phases for a set of high quality subduction events. These relationships are used in the framework ...
