Well-controlled exchange bias effect in MnO@Mn3O4 core-shell nanoparticles with an inverted coupling structures
The influence of the varied thickness of antiferromagnetic (AFM) and ferrimagnetic (FiM) nanostructure in MnO@Mn3O4 core-shell nanoparticles (NPs) on the exchange bias effect has been investigated. The MnO@Mn3O4 core-shell NPs with varied radius of MnO core (R MnO ) and thickness of Mn3O4 shell (T M...

| description | The influence of the varied thickness of antiferromagnetic (AFM) and ferrimagnetic (FiM) nanostructure in MnO@Mn3O4 core-shell nanoparticles (NPs) on the exchange bias effect has been investigated. The MnO@Mn3O4 core-shell NPs with varied radius of MnO core (R
MnO
) and thickness of Mn3O4 shell (T
Mn3O4
) have been synthesized by in-situ oxidation of the pure MnO NPs in organic solution containing a mild oxidant at different temperatures. The exchange bias effect can be tuned by changing the R
MnO
(T
Mn3O4
) of the MnO@Mn3O4 core-shell NPs. The strongest exchange coupling effect of both 17.2 and 25.0 nm MnO@Mn

in inverted core-shell NPs is helpful for the further understanding of the exchange bias mechanism. |
