الوصف: MnO2 nanostructures were fabricated by plasma assisted‐chemical vapor deposition (PA‐ CVD) using a fluorinated diketonate diamine manganese complex, acting as single‐source precursor for both Mn and F. The syntheses were performed from Ar/O2 plasmas on MgAl2O4(100), YAlO3(010), and Y3Al5O12(100) single crystals at a growth temperature of 300 °C, in order to investigate the substrate influence on material chemico‐physical properties. A detailed characterization through complementary analytical techniques highlighted the formation of highly pure and oriented F‐doped systems, comprising the sole β‐MnO2 polymorph and exhibiting an inherent oxygen deficiency. Optical absorption spectroscopy revealed the presence of an appreciable Vis‐light harvesting, of interest in view of possible photocatalytic applications in pollutant degradation and hydrogen production. The used substrates directly affected the system structural features, as well as the resulting magnetic characteristics. In particular, magnetic force microscopy (MFM) measurements, sensitive to the out‐of‐plane magnetization component, highlighted the formation of spin domains and long‐range magnetic ordering in the developed materials, with features dependent on the system morphology. These results open the door to future engineering of the present nanostructures as possible magnetic media for integration in data storage devices.
