CoFe2O4 and CoFe2O4‐SiO2 Nanoparticle Thin Films with Perpendicular Magnetic Anisotropy for Magnetic and Magneto‐Optical Applications

“…Absorption spectra are obtained by subtracting the transmission from 100% ( Figure 5 a,b). Refractive indices are extracted from the refl ectance spectra in the 300-500 nm wavelength range, corresponding to high and medium absorption regions [ 27 ] for samples with up to 50 wt% SiO 2 content (absorption, A > 30%). The equation αd = −ln[( T /(1− R )] is used to calculate the absorption coeffi cient ( α ) of the samples.…”

Optical bandgap and ferroelectric studies of Pb0.8−y La y Co0.2TiO3 (y = 0.2 to 0.8) synthesized by microwave irradiation processed sol-gel technique

“…But interestingly, the increase of optical bandgap ∼3.44 eV was achieved for y=0.8 composition which may be attributed to the enriched La-content. In this study, the obtained wide bandgap value for y=0.8 composition may be argued due to the cation exchange [16]. In general, it can be expected that the microwave heating could be responsible for increase of E op value for the same composition.…”

Liquid-phase deposition of ferroelectrically switchable nanoparticle-based BaTiO3 films of macroscopically controlled thickness

“…Such optical properties make both, the BaTiO 3 nanoparticles and the nanoparticle-based films promising candidates for future devices in the field of electrooptics 67 and integrated optics, as the single phase as well as the constituent in multiferroic composite materials. 68 A more detailed discussion of the optical characterization and porosity of BaTiO 3 films fabricated from dispersions with varying nanoparticle concentrations is given in the ESI, † Fig. S3b and c.…”
