Processos de magnetização e magnetoimpedância em filmes com exchange bias
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2006-10-20)
In this work, the magnetization process and the magnetoimpedance effect in thin films with exchange bias were studied. We have investigated NiO/NiFe and NiFe/FeMn/Ta multilayer produced by magnetron sputtering on glass and ...
Exchange-biased SiO2/Co/CoO granular multilayers deposited by sequential sputtering
(Elsevier, 2017-10-01)
Nucleation of vortex pairs in exchange biased nanoelements
(American Institute of Physics, 2011-03-24)
Enhanced positive and negative exchange bias in FeF2/Ni with dusted interfaces
(American Institute of Physics, 2020)
An enhanced exchange bias was found in FeF2/Ni interfaces by inserting dusting of Pd and Cu atoms. We have used an ultrathin wedge to investigate systematically the effect of a discontinuous nonmagnetic spacer between the ...
Training-induced Inversion Of Spontaneous Exchange Bias Field On La1.5ca0.5comno6
(Elsevier Science BVAmsterdam, 2017)
Perpendicular exchange bias in IrMn/Pt/[Co/Pt](3) multilayers with cone magnetization
(ELSEVIER SCIENCE SA, 2011)
The perpendicular exchange bias and magnetic anisotropy were investigated in IrMn/Pt/[Co/Pt](3) multilayers through the analysis of in-plane and out-of-plane magnetization hysteresis loops. A phenomenological model was ...
Compensation temperatures and exchange bias in La1.5Ca0.5CoIrO6
(American Physical Society, 2016-05)
We report on the study of magnetic properties of the La1.5Ca0.5CoIrO6 double perovskite. Via ac magnetic susceptibility we have observed evidence of weak ferromagnetism and reentrant spin glass behavior on an antiferromagnetic ...
Estudo do exchange bias em filmes finos de NiFe/FeMn (bicamadas) e NiFe/IrMn (multicamadas)
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 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 ...
Angular dependent FORC and FMR of exchange-biased NiFe multilayer films
(IOP Publishing, 2017-01-24)
Dynamic ferromagnetic resonance (FMR, X-band 9.8 GHz) and static first-order reversal curve (FORC) techniques are combined to study the intrinsic exchange-bias distribution via measurements of in-plane angular variation ...
Uncompensated magnetization and exchange-bias field in La 0.7Sr0.3MnO3/YMnO3 bilayers: The influence of the ferromagnetic layer
(Elsevier Science, 2011-11)
We studied the magnetic behavior of bilayers of multiferroic and nominally antiferromagnetic o-YMnO3 (375 nm thick) and ferromagnetic La 0.7Sr0.3MnO3 and La0.67Ca 0.33MnO3 (8...225 nm), in particular the vertical magnetization ...
