Fabrication of large‐area transparent conducting electrodes (TCEs) of high performance through cost‐effective high throughput methods has been an area of intensive research. In this context, the fabrication of flexible, 25 cm2 wide TCEs with high figure of merit (FoM) (≈494 Ω−1 ) is achieved by two roll‐to‐roll compatible processes, namely screen printing and spray coating, by suitably modifying crackle lithography in a cost‐effective manner. The fabricated TCEs exhibit low sheet resistance (<10 Ω □−1) and high transmittance (≈86–90%) in the visible region. The TCEs are shown to be highly bendable, the change in the sheet resistance is only ≈2% up on 6000 bending cycles. The application of these TCEs as transparent bendable uniform Joule heaters and surface capacitive touchscreens has also been demonstrated. The TCEs are, thus, just as good as any TCE produced using spin‐coating or similar small area coating techniques.

Different layer thicknesses of Cobalt ranging from 2.6Å (1.5 ML) up to 55Å (30.5 ML) deposited on ferroelectric BaTiO3 have been studied regarding their magnetic behavior. The layers have been characterized using XMCD spectroscopy at remanent magnetization. After careful data analysis the magnetic moments of the Cobalt could be determined using the sum rule formalism. There is a sudden and abrupt onset in magnetism starting at thicknesses of 9Å (5 ML) of Cobalt for measurements at 120 K and of 10Å (5.5 ML) if measured at room temperature. Initial island growth and subsequent coalescence of Co on BaTiO3 is suggested to explain the sudden onset. In that context, no magnetically dead layers are observed.

The growth and magnetic properties of ultrathin iron oxide films on BaTiO3(001) substrate have been studied by low energy electron diffraction, x-ray absorption spectroscopy (XAS), x-ray magnetic circular dichroism (XMCD), and magneto-optic Kerr effect experiments. The iron oxide films were prepared by both simultaneous oxidation and postgrowth oxidation methods. Assuming a surface structure close to Fe3O4[100], the unit cell was found to be epitaxially grown on BaTiO3[100] unit cell due to small lattice mismatch between the film and the substrate. The films exhibit a uniaxial magnetic anisotropy with the easy-axis along Fe3O4[11¯0] direction. For the films on or above 1.7 nm thickness, the XMCD shows characteristic contributions from different Fe site occupations similar to those of the bulk Fe3O4. On the other hand, the XAS line shape and XMCD of the films in the thickness range 1.2–1.6 nm indicate the lesser occupation of Fe2+ octahedral sites associated with the formation of γ-Fe2O3 phase at lower thicknesses. Our investigations offer further insight into the structure, interface, and magnetic properties of the Fe3O4/BaTiO3 as an interesting system for technological applications.
