The bulk and emerging interface properties of magnetite Fe3O4/YSZ(001) heterostructures grown by pulsed laser deposition are investigated. Fe3O4 thin films (4–38 nm) grow epitaxially in (111) orientation and undergo a Verwey transition at max. TV =

Magneto-ionic control of magnetism is a promising route toward the realization of non-volatile memory and memristive devices. Magneto-ionic oxides are particularly interesting for this purpose, exhibiting magnetic switching coupled to resistive switc

Resistive switching in metal oxides is related to the migration of donor defects. Here Baeumer et al. use in operandoX-ray spectromicroscopy to quantify the doping locally and show that small local variations in the donor concentration result in larg

In this study, we investigated the electronic surface structure of donor-doped strontium titanate. Homoepitaxial 0.5 wt. % donor-doped SrTiO3 thin films were analyzed by in situ near ambient pressure X-ray photoelectron spectroscopy at a temperatu

The surface electronic structure of a material is frequently used to identify simple descriptors for its catalytic efficacy and other properties. To harness the predictive ability of such descriptors, structural and chemical evolutions of the materia
