Las ferritas (MFe2O4) son una de las familias de materiales magnéticos más estudiados tanto desde el punto de vista básico como aplicado. Las ferritas cristalizan en la estructura espinela y poseen dos sitios para los cationes, A y B. Esta característica hace que sus propiedades magnéticas de estos óxidos dependan de la distribución de cationes en las subredes de sitios A y B. El acoplamiento...
I will show concluded and current experimental work done at the Center for Quantum Devices, Copenhagen [1,2] and at CEA, Grenoble [3,4]. The work is based on electrical measurements at (sub-Kelvin) dilution-refrigerator temperatures on devices based on individual semiconductor nanowires with epitaxially-grown superconductors. Single electron spins can be confined in the nanowires, and their...
The adaptability of synthetic antiferromagnets (SAF) in spintronic devices based on spin Hall effects has emerged during the last years. In this work we report the use of a SAF (antiferromagnetically exchange coupled Co/Ru/Co) as a spin current injector and the observation of spin pumping and inverse spin Hall effect in [SAF]/Pt heterostructures [1,2]. By exploiting the interlayer exchange...
En el presente trabajo, a partir del estudio estructural y magnético de la aleación AlxFe(1-x) con x=0,25; 0,5 y 0,75, se plantea el Hamiltoniano magnético. Primero las muestras fueron sintetizadas por la técnica de horno de arco (HA) y posteriormente fueron tratadas a las temperaturas de 600 C, 950C y 1000C por 48, 290 y 48 horas respectivamente. Después del tratamiento térmico...
Two dimensional materials have provided unique insights in condensed matter physics, yielding a multitude of novel effects. Among them, graphene has shown to be an outstanding material owing to its exceptional and tunable electrical properties. In graphene, spin information can propagate over long distances and also be manipulated by proximity induced phenomena [1,2,3], providing thus the...
Classical and quantum mechanical models of a beam splitter are addressed, including the cases where there are one or two input source(s) of light resulting in two consequent output beams. In the classical case we invoke the conservation of energy to derive a $2 \times 2$ matrix $M_{bs}$ which transforms the electric fields. In the quantum mechanical case we invoke conservation of probability...
Two-dimensional (2D) atom-thick crystals such as graphene, boron-nitrade (BN), transition metal dichalcogenides (TMDC) and most recently phosphorus allotropes have drawn both experimental and theoretical interest due to their unique electronic and optical properties. For instance, TMDCs possess remarkable properties concerning the tunability of band gap and strong light-matter coupling that...
Presentamos y analizamos las características de transmitancia de sensores de desplazamiento basados en fibras ópticas monomodo afinadas y curvadas en forma de S. Comparamos la sensibilidad del sensor de fibra afinada curvada en S con respecto a la sensibilidad de la fibra afinada sin curvatura previa. Los resultados muestran sensibilidades de hasta 192 pm/µm para los sensores tipo S con...
Due to their interest in both experimental and theoretical study of the structural and electronic properties as multiferroic materials, the compounds YFexCr1-xO3 (x = 0.25, 0.50, 0.75 and 1) were prepared by autocombustion. They were analyzed using techniques that provide information both at the atomic and macroscopic level, including low temperature neutron diffraction, 57Fe Mössbauer...
Monte Carlo simulation method is used to detect the dynamic behavior of nanoscale water confined by a SiO2 foundation bed and a gold probe.The distance of the gap between these two solid bondaries is varied during the simulations. This study focuses on the potential formation of finger-like water bridges that may onset when the gap distance becomes very small. We seek to establish correlation...
This paper describes the process of synthesis of the polycrystalline zeolitic imidazolate framework-67 (ZIF-67), in which it was performed by hand milling, followed by centrifugation under an ethanol solution and free of irradiation assisted. X-ray diffraction analysis shows that the ZIF-67 has a cubic crystalline structure centred with lattice parameter of 17.01 Å frame type generating hollow...
