Instabilities of spin torque driven auto-oscillations of a ferromagnetic disk magnetized in plane
(Amer Physical Soc., 2016)
The stability of the magnetization auto-oscillations of the ferromagnetic free layer of a cylindrical nanopillar structure is studied theoretically using a classical Hamiltonian formalism for weakly interacting nonlinear ...
Propriedades magnéticas quase-estáticas de filmes ferromagnéticos amorfos de FeCuNbSiB
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em FísicaFísica da Matéria Condensada; Astrofísica e Cosmologia; Física da Ionosfera, 2012-07-27)
Today, one of the topics that attracts interest of the scientific community is the understanding of magnetic properties of magnetic systems with reduced dimensions, in particular, ferromagnetic thin films. In this case, ...
Wrinkled labyrinths in critical demixing ferrofluid
(Royal Society of Chemistry, 2017-01)
A thin film of a critical ferrofluid mixture undergoes a sequence of transitions in a magnetic field. First the application of a field induces a critical demixing of the fluid into cylindrical droplets of the minority phase ...
QUANTUM HALL FERROMAGNET IN A DOUBLE WELL WITH VANISHING g-FACTOR.
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2009)
We have studied the quantum Hall effect in Al(x)Ga(1-x)As-double well structure with vanishing g-factor. We determined the density-magnetic field n(s) - B diagrams for the longitudinal resistance R(xx). In spite of the ...

Domain imaging in FINEMET ribbons
(Elsevier Science, 2010-09)
The magnetization behaviour of a ferromagnetic material depends on its domain structure, which in turn is largely determined by magnetic anisotropies. In this work, domain patterns were observed by a quite forgotten but ...
Magnetic reconfiguration of MnAs/GaAs(001) observed by magnetic force microscopy and resonant soft x-ray scattering

Síntese, sinterização e caracterização de ferritas à base de Ni-Zn
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em QuímicaFísico-Química; Química, 2008-09-24)
Were synthesized different ferrites NixZn1-xFe2O4 (0,4 ≤ x ≤ 0,6) compositions by using citrate precursor method. Initially, the precursors citrates of iron, nickel and zinc were mixed and homogenized. The ...
Síntese análise das propriedades magnéticas da ferrita de NiMg e características de absorção de radiação
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em QuímicaFísico-Química; Química, 2008-04-18)
It was synthesized different Ni1-xMgxFe2O4 (0,2 ≤ x ≤ 0,7) compositions by use of citrate precursor method. Initially, the precursory citrates of iron, nickel and magnesium were mixed and homogenized. The ...
