Temperature-dependent magnetic properties of Ni nanotubes synthesized by atomic layer deposition
(2016)
Highly-ordered and conformal Ni nanotube arrays were prepared by combining atomic layer deposition (ALD) in a porous alumina matrix with a subsequent thermal reduction process. In order to obtain NiO tubes, one ALD NiCp2/O-3 ...
Stability of atomic-sized skyrmions in antiferromagnetic bilayers
(2019)
We perform a stability analysis of an isolated atomic-sized antiferromagnetic skyrmion (AFM-Sk), formed on the superior layer of a magnetic bilayer. The coupling between both square lattices acts as an effective staggered ...
Piezospintronic effect in honeycomb antiferromagnets
(2017)
The emission of pure spin currents by mechanical deformations, the piezospintronic effect, in antiferromagnets is studied. We characterize the piezospintronic effect in an antiferromagnetic honeycomb monolayer in response ...
Dynamical quenching of tunneling in molecular magnets
(2015)
It is shown that a single molecular magnet placed in a rapidly oscillating magnetic field displays the phenomenon of quenching of tunneling processes. The results open a way to manipulate the quantum states of molecular ...
Effect of annealing atmosphere on phase formation and electrical characteristics of bismuth ferrite thin films
(Pergamon-Elsevier B.V. Ltd, 2009-08-05)
Bismuth ferrite thin films were deposited on Pt/Ti/SiO(2)/Si substrates by a soft chemical method and spin-coating technique. The effect of annealing atmosphere (air, N(2) and O(2)) on the structure and electrical properties ...
Dynamical aspects of the unzipping of multiwalled boron nitride nanotubes
(Royal Soc Chemistry, 2013-01-01)
Boron nitride nanoribbons (BNNRs) exhibit very interesting magnetic properties, which could be very useful in the development of spintronic based devices. One possible route to obtain BNNRs is through the unzipping of boron ...
Chiral magnetic chemical bonds in molecular states of impurities in Weyl semimetals
(2019-12-01)
We demonstrate that chirality of the electron scattering in Weyl semimetals leads to the formation of magnetic chemical bonds for molecular states of a pair of impurities. The effect is associated with the presence of ...
Ultrafast domain wall propagation due to the interfacial Dzyaloshinskii-Moriya interaction
(IOP Publishing, 2020)
It is shown that the interplay between curvature and interfacial Dzyalonshinsky-Moriya interaction (DMI) is a pathway to ultrafast domain wall (DW) dynamics in ferromagnetic nanotubes. In this work, we theoretically study ...
Magnetostatic interaction between two bubble skyrmions
(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 ...
Structural and electrical properties of Co-doped ZnO prepared by DC-Magnetron co-sputtering for spintronic applications
(Universidad Nacional de ColombiaBogotá - Ciencias - Maestría en Ciencias - FísicaDepartamento de FísicaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2021-06-09)
In this work, the e ect of Cobalt in ZnO thin lms was studied. The samples were synthesized
by DC-Magnetron co-sputtering over di erent substrates (Glass, Al2O3, ITO, Si,
and Au). Structural and electrical properties ...
