Efeitos de interações de curto alcance e tamanho de clusters em sistemas desordenados
(Universidade Federal de Santa Maria, 2015-08-04)
The competition between cluster spin glass and ferromagnetism or antiferromagnetism
is studied in this work. The model considers clusters of spins with short-range
ferromagnetic or antiferromagnetic interactions (J0) and ...
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 ...
Análise de populações estelares e subestruturas em aglomerados de galáxias
(Universidade Federal de Santa Maria, 2015-08-25)
In this work, we investigated differences between stellar populations of galaxies that are part
of a cluster with and without substructures. We used optical spectra obtained from Sloan Digital
Sky Servey III DR10 for the ...
