Ferromagnetic insulating epitaxially strained La₂NiMnO₆ thin films grown by sputter deposition

Ferromagnetic insulating state in tensile-strained LaCoO3 thin films from LDA+U calculations

With local density approximation+Hubbard U (LDA+U ) calculations, we show that the ferromagnetic (FM) insulating state observed in tensile-strained LaCoO3 epitaxial thin films is most likely a mixture of low-spin (LS) and high-spin (HS) Co, namely, a HS/LS mixture state. Compared with other FM states, including the intermediate-spin (IS) state (metallic within LDA+U ), which consists of IS Co o...

Photothermally modulated ferromagnetic resonance investigations of epitaxially grown thin Fe (001) films

The photothermally modulated (PM) ferromagnetic resonance (FMR) combines the high sensitivity of conventional FMR and the spatial resolution of thermal waves. For the first time, this alternative FMR-technique was applied to the magnetic characterization of high-quality thin Fe (001) films epitaxially grown on (001) GaAs substrate: Images of the distribution of crystalline anisotropy constant K...

Positive magnetoresistance in ferromagnetic Nd-doped In2O3 thin films grown by pulse laser deposition

Sputter deposition of calcium phosphate/titanium dioxide hybrid thin films

The application of either hydroxyapatite (HA) or titanium dioxide (TiO2) as coatings onto existing bioinert materials has been explored as the key route for enhancing the surface properties of hard tissue implant devices. However, it has been proposed that composite HA/TiO2 coatings may provide significant advantages for the application of such surfaces. This work reports on the surface propert...

Properties of SnS thin films grown by physical vapour deposition

Thin films of tin sulfide (SnS) were prepared by thermal evaporation technique on glass substrates and on n-type Si substrate and their physical properties were studied. The phase of the obtained thin films before and after thermal treatment was confirmed by X-ray diffraction analysis and Raman spectra. Optical transmission and reflection spectra were measured in the wavelength range 300-1800 n...
