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 ...
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 ...
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 ...

Surface states of FeF2 (110) and its uncompensated magnetization
(Elsevier, 2015)
The (110) surface of iron fluoride (FeF2) is especially relevant to the understanding of the exchange bias phenomenon, which has important applications in the sensor industry, and has been extensively explored, both ...
Training-induced Inversion Of Spontaneous Exchange Bias Field On La1.5ca0.5comno6

Reversed exchange-bias effect associated with magnetization reversal in the weak ferrimagnet LuF e0.5 C r0.5 O3
(American Physical Society, 2018-03)
The exchange-bias (EB) effect with sign reversal was found in LuFe0.5Cr0.5O3 ferrite-chromite, which is a weak ferrimagnet below TN=265K, exhibiting antiparallel orientation of the ferromagnetic (FM) moments of the Fe and ...
Propriedades físicas de bicamadas magnéticas
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em FísicaFísica da Matéria Condensada; Astrofísica e Cosmologia; Física da Ionosfera, 2007-03-21)
The magnetic order of bylayers composed by a ferromagnetic film (F) coupled with an antiferromagnetic film (AF) is studied. Piles of coupled monolayers describe the films and the interfilm coupling is described by an ...
Dipole-induced exchange bias
(2017)
The discovery of dipole-induced exchange bias (EB), switching from negative to positive sign, is reported in systems where the antiferromagnet and the ferromagnet are separated by a paramagnetic spacer (AFM-PM-FM). The ...
