The magnetic properties of Fe3−δO4 nanoparticles for medical applications dependon the synthesis route influencing their defect structure, ligand shelland shape [1]. Optimisation of the magnetisation requires disentanglingpreparation-specific influences from intrinsic size effects. [...]

In La0.7Sr0.3MnO(3-δ) (LSMO), the topotactic phase transition from the Perovskite(PV) phase to the layered oxygen-vacancy-ordered Brownmillerite (BM)phase can be triggered by deoxygenation. We realized this phase transition inboth a strained LSMO thin film system and bulk-like unstrained LSMO powdersystem via assisted thermal vacuum annealing. [...]

Resistive switching implies that the device can be switched between aHigh ResistanceState (HRS) and Low Resistance State (LRS) upon application of an electricfield. Fe3O4 emerges as a candidate for resistive switching due to the sensitivityof its magnetic and electronic properties on the presence of oxygen vacancies.Here we present the preparation and characterization of epitaxial Fe3O4 thinfilms grown on TiO2 - terminated Nb:SrTiO3 via pulsed laser deposition (PLD).We observe resistive switching using I-V measurements and magnetometry. [...]

Heterostructures (HS) based on superconductors and ferromagnets exhibitstrong potential for innovating devices in spintronics and quantum comput-ing applications. SrRuO3 (SRO) has attracted much attention among transitionmetal oxides for being the only 4d oxide to show itinerant ferromagnetism andmetallic conductivity [...]

The use of curved surfaces as substrates for thin film deposition induces lateralvariation in film thickness, which allows variation in the deposited materialproperties. [Co/Pd]n multilayers with differen Co thicknesses were depositedon a flat silicon substrate, and densely packed two-dimensional arrays of silicananospheres with different radii of curvature formed by improved drop-castingmethod [1] [...]

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. [...]
