Yttrium iron garnet heterocoagulated by silica
(2002-01-01)
There are several reasons to make to cover magnetic materials with shells of different chemical composition. One is to change physical (optical, magnetic, conductive, etc.) and/or chemical properties of dispersions by ...
Modos massivos e paredes de domínio em líquidos de Fermi
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2018-06-11)
In this thesis, we use Fermi liquid theory to deal with three problems. The first and second problems are about a direct and an indirect detection of the amplitude massive ‘‘Higgs’’ mode in weak ferromagnets like ZrZand M ...
Tailoring the ground state of the ferrimagnet La2Ni(Ni1/3Sb2/3)O6
(Elsevier Science, 2013-07)
We report on the magnetic and structural properties of La2Ni(Ni1/3Sb2/3)O6 in polycrystal, single crystal and thin film samples. We found that this material is a ferrimagnet (Tc≈100 K) which possesses a very distinctive ...
Comportamiento crítico de láminas ferromagnéticas ultradelgadas
(2009-08)
Las láminas ferromagnéticas ultradelgadas son sistemas magnéticos caracterizados por una fuerte anisotropía uniaxial producto del confinamiento del sistema en una de sus direcciones. Ésta favorece el alineamiento de los ...
Angular dependence of the magnetic properties of permalloy and nickel nanowires as a function of their diameters
(IOP Publishing, 2018-01-19)
In this paper we have compared the angular dependence of the magnetic properties of permalloy (Ni80Fe20) and nickel nanowires by means of micromagnetic simulations. For each material we have chosen two diameters, 40 and ...
