Intrinsic perpendicular anisotropy and exchange biasing in CoO/permalloy multilayers
نویسندگان
چکیده
For permalloy/CoO multilayers, the exchange field and the coercivity of the perpendicular and longitudinal exchange biasing have been found to decrease with increasing temperature. After zero field cooling, perpendicular magnetic anisotropy is observed. For small permalloy layer thickness, perpendicular anisotropy film can be established at low temperatures. r 2004 Elsevier B.V. All rights reserved. PACS: 75.70 i; 75.30.Et; 75.70.Cn

Effects of cooling field strength on exchange anisotropy at permalloy/CoO interfaces
We have studied exchange anisotropy at ferromagnet/antiferromagnet ~FM-AFM! interfaces as a function of cooling field in Ni80Fe20 ~permalloy! films deposited on bulk single-crystal CoO substrates. Hysteresis loops measured after cooling through the antiferromagnetic ordering temperature in different magnetic fields show that the exchange bias has little dependence on cooling field. Large coolin...
متن کاملOscillatory interlayer exchange coupling and its temperature dependence in [Pt/Co]3/NiO/[Co/Pt]3 multilayers with perpendicular anisotropy.
Interlayer exchange coupling that oscillates between antiferromagnetic and ferromagnetic as a function of NiO thickness has been observed in [Pt(5 A)/Co(4 A)](3)/NiO(t(NiO) A)/[Co(4 A)/Pt(5 A)](3) multilayers with out-of-plane anisotropy. The period of oscillation corresponds to approximately 2 monolayers of NiO. This oscillatory behavior is possibly attributed to the antiferromagnetic ordering...
متن کاملIncreased exchange anisotropy due to disorder at permalloy/CoO interfaces
The exchange anisotropy of Nis&Je,, (permalloy) films deposited onto bulk single crystal Co0 substrates using molecular-beam epitaxy is strongly affected by the interface structure. Contrary to expectations for uncompensated interfaces, the loop shift increases for samples with greater interface disorder. The results are discussed in the light of proposed exchange anisotropy models. The results...
متن کاملMagnetic reversal of perpendicularly-biased Co/Pt multilayers
We have investigated the magnetic reversal behavior of [(Co/Pt)4Co/CoO]N multilayers that are exchange biased perpendicular to the film plane. We find clear differences in the nucleation properties of the reverse domains of the ascending and descending branches of the hysteresis loops. However, the evolution of the reverse domains, once nucleated, are symmetric to positive and negative field sw...
متن کاملExchange coupling mechanism for magnetization reversal and thermal stability of Co nanoparticles embedded in a CoO matrix
A model providing a semi-quantitative account for the magnetic behavior of Co nanoparticles embedded in a CoO matrix is presented. The results confirm that exchange coupling at the interface between FM and AFM nanostructures, could provide an extra source of magnetic anisotropy, leading to thermal stability of the FM nanoparticles. It is shown that perpendicular coupling between the AFM and FM ...
