Tuning the magnetic properties of Fe3O4 thin films driven by electric field
202487th Annual Meeting of the DPG and DPG Spring Meeting 2024 of the Condensed Matter Section (SKM), TU BerlinTU Berlin, Germany, 17 Mar 2024 - 22 Mar 20242024-03-172024-03-22
Tuning magnetic oxide phases at heterointerfaces is a compelling strategy foradvancing spintronic and memristive device applications. Specifically for ironoxides, we have shown that we can tune themagnetic and electrical properties ofthin films upon initiating a phase transition between magnetite, maghemite andwustite. [...]

Structural and magnetic characterization of FeOx nanoparticle dispersions upon freezing and melting
202487th Annual Meeting of the DPG and DPG Spring Meeting 2024 of the Condensed Matter Section (SKM), TU BerlinTU Berlin, Germany, 17 Mar 2024 - 22 Mar 20242024-03-172024-03-22
We have studied the structural and magnetic properties of magnetic nanoparticledispersions upon cooling and heating over the solvent melting temperature.The particles consist of iron oxide dispersed in water or toluene with diametersranging from 10 to 20 nm. The magnetic properties were studied using SQUIDmagnetometry employing zero field cooled (ZFC)/field cooled (FC) magnetizationcurves at different fields and hysteresis curves. [...]
