Exchange bias em multicamadas de NiFe/IrMn/Ta: um estudo através da magnetorresistência anisotrópica
(Universidade Federal de Santa Maria, 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 ...
Estudo do exchange bias em filmes finos de NiFe/FeMn (bicamadas) e NiFe/IrMn (multicamadas)
(Universidade Federal de Santa Maria, 2016-03-23)
The Exchange Bias (EB) phenomenon consists of an interfacial exchange coupling between a ferromagnetic (FM) material and an antiferromagnetic (AFM) one and has as the main characteristics the rise of a unidirectional ...
Multicamadas de NiFe/FeMn com potencial de aplicação como sensores a altas frequências
(Universidade Federal de Santa Maria, 2016-02-12)
In this work we investigated the magnetization process and the magnetoimpedance in samples exhibiting exchange bias. Ni81Fe19=Fe50Mn50=T a bilayers and multilayers where
grown onto glass substrates. The exchange bias was ...
Estudo de exchange bias via magnetorresistência anisotrópica
(Universidade Federal de Santa Maria, 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 ...
