Observation of a gel of quantum vortices in a superconductor at very low magnetic fields
(American Physical Society, 2020-03)
A gel consists of a network of particles or molecules formed for example using the sol-gel process, by which a solution transforms into a porous solid. Particles or molecules in a gel are mainly organized on a scaffold ...
Magnetic characterization by SQUID and FMR of a biocompatible ferrofluid based on Fe(3)O(4)
(IOP PUBLISHING LTD, 2009)
Biocompatible superparamagnetic iron oxide nanoparticles of magnetite coated with dextran were magnetically characterized using the techniques of SQUID (superconducting quantum interference device) magnetometry and ...
Cation distribution and magnetic characterization of the multiferroic cobalt manganese Co2MnO4 spinel doped with bismuth
(2013-03-01)
The structural and magnetic properties of the cubic spinel oxide Co 2MnO4 (Fd3m space group) doped with different concentrations of bismuth, were investigated by X-ray diffraction and SQUID magnetometry. The Bi3+ ions ...

Superconducting nanowire fiber mats and the paramagnetic Meissner effect
(2021-01-01)
Superconducting nanowire fiber mats of Bi2Sr2CaCu2O8, YBa2Cu3O7 and GdBa2Cu3O7 were fabricated using electrospinning and solution blow-spinning. Fiber mats consisting of individual nanowires with long lengths (∼100 μm) and ...
Synthesis and characterization of Cu2+ substituted magnetite
(SPRINGER, 2011-11-01)
Samples of magnetite, both pure and doped with divalent copper, Fe3-xCuxO4, with x = 0, 0.05, 0.10 and 0.20 atm.%, were synthesized hydrothermally. The samples were characterized by Atomic Absorption Spectroscopy, Mössbauer ...
Electrodeposition of nickel nanoparticles and their characterization
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2006-12-01)
Electrodeposition of nickel nanoparticles on indiumtin oxide (ITO) substrate is achieved
by an alternative electrochemical method in which pulsed current is applied. Determin-
ation of the nucleation mechanism of the ...
Enhancement of the critical current density by increasing the collective pinning energy in heavy ion irradiated Co-doped BaFe2As2 single crystals
(IOP Publishing, 2015-05-08)
We investigate the effect of heavy ion irradiation (1.4-GeV Pb) on the vortex matter in Ba(Fe0.92Co0.08)2As2 single crystals by SQUID magnetometry. The defects created by the irradiation are discontinuous amorphous tracks, ...
Hyperfine and magnetic properties of a YxLa1-xFeO3 series (0<x<1)
(Elsevier, 2015-01-12)
A series of orthoferrites YxLa1-xFeO3 in the entire range of composition was synthesized at room temperature by mechanochemical activation of oxide mixtures. Phase composition, structure and microstructure of the obtained ...
