Rotor Demagnetization Effects on Permanent Magnet Synchronous Machines
(Elsevier, 2013-10)
The effects of asymmetrical magnet faults on the rotor of permanent magnet synchronous machines (PMSM) are analyzed in the present work. Two different stator winding configurations, series and parallel connected windings, ...
Dipolar interaction and demagnetizing effects in magnetic nanoparticle dispersions: Introducing the mean-field interacting superparamagnet model
(American Physical Society, 2017-04)
Aiming to analyze relevant aspects of interacting magnetic nanoparticle systems (frequently called interacting superparamagnets), a model is built from magnetic dipolar interaction and demagnetizing mean-field concepts. ...
Effective demagnetizing tensors in arrays of magnetic nanopillars
(Physical Review B, 2018)
Espalhamento ressonante de raios X aplicado ao estudo de nano-estruturas
(Universidade Federal de Minas GeraisUFMG, 2008-04-10)
In this thesis, resonant X-ray scattering techniques were used to study two different systems. First, grazing incidence difraction associated with dispersion corrections in the atomic scattering factor were employed to ...
Dipolar interactions among magnetic dipoles of iron oxide particles dispersed in mili-size hydrogel beads
(Elsevier Science, 2020-11-01)
The recently published Mean Field Interacting Superparamagnet Model (MFISP model), whichintroduces the effective demagnetizing factor , is tested in specimens having a random-likespatial distribution of magnetic nanoparticles, ...
New late Proterozoic paleomagnetic pole for the Rio de la Plata craton: Implications for Gondwana
(Elsevier Science, 2006-07)
Major uncertainties remain on the precise kinematic and temporal aspects of Gondwana assembly. In order to provide new constraints on them, a paleomagnetic study was carried out on the Ediacaran succession of red claystones ...
