TL;DR: In this article, the chemical state of oxygen, aluminum and zinc in Al-doped ZnO (ZAO) films was investigated by X-ray photoelectron spectroscopy (XPS), as well as the transition zone of the film-to-substrate, by auger electron spectrography (AES), showing that zinc remains mostly in the formal valence states of Zn2+.

TL;DR: In this paper, the micro-Raman scattering spectra of the films were compared to the results obtained by annealing the as-deposited VO 2 (B) film and the surface of the annealed film consisted of three regions of the black V 6 O 13 region, the yellow VO 2(B) region and the white non-crystalline region.

TL;DR: Tetrahedral amorphous carbon (ta-C) films have been prepared by filtered arc deposition (FAD) and the structure of the ta-C films was characterised by Raman Spectroscopy.

TL;DR: In this paper, a trilayer magnetic structure, consisting of a heavy metal (Platinum) as a buffer, an ultrathin ferromagnet (Cobalt) as functional layer, and an antiferromagnetic insulator (Nickel oxide, NixOy) as capping, is a host of intriguing physical phenomena desirable for spintronics.

TL;DR: In this article, a focused ion beam was applied to selectively illuminate patterned regions in a Pt/Co/MgO strip with perpendicular magnetic anisotropy, soften the illuminated areas, and realize the gradual magnetization switching by spin-orbit torque (SOT) driven nucleation process.
