Exchange bias perpendicular em multicamadas de IrMn/Co/Pd
(Universidade Federal de Santa MariaBrasilFísicaUFSMPrograma de Pós-Graduação em FísicaCentro de Ciências Naturais e Exatas, 2023-04-26)
Magnetic skyrmions are spin textures that can arise in thin films that exhibit the Dzyaloshinskii–Moriya interaction. Such interaction emerges from symmetry breaking at the interface
between a ferromagnetic material and ...
Origin of spin-glass and exchange bias in La1-3Sr2-3FeO3−γ nanoparticles
(AIP Publishing, 2014-03-18)
Tuning the Exchange Bias on a Single Atom from 1 mT to 10 T
(American Physical Society, 2019-06)
Shrinking spintronic devices to the nanoscale ultimately requires localized control of individual atomic magnetic moments. At these length scales, the exchange interaction plays important roles, such as in the stabilization ...
Estudo de exchange bias via magnetorresistência anisotrópica
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2013-08-15)
Anisotropic magnetoresistance (AMR) corresponds to the change of R in an ferromagnetic
material with the angle between electric current and magnetization. Sensors using this
effect are suited to detect both angular and ...
Exchange bias em multicamadas de NiFe/IrMn/Ta: um estudo através da magnetorresistência anisotrópica
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2015-08-07)
In this work a study of the exchange interaction between ferromagnetic (NiFe) and antiferromagnetic
(IrMn) layers was done through structural, magnetic and electric characterization.
NiFe/IrMn/Ta films were grown with ...
Magnetoimpedância em multicamadas de Ni81Fe19/Ir50Mn50

Estudo da anisotropia unidirecional e da histerese rotacional em sistemas com exchange bias
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2014-08-18)
The exchange bias (EB) phenomen occurs due to the coupling between ferromagnetic and
antiferromagnetic material and the main characteristics are the rise of unidirectional anisotropy
and the rotational hysteresis in torque ...
A disorder induced mechanism for positive exchange bias fields
(American Physical Society, 2013-07-18)
We propose a mechanism to explain the phenomenon of positive exchange bias on magnetic bilayered systems. The mechanism is based on the formation of a domain wall at a disordered interface during field cooling, which ...
