For Co2Fe6B2–MgO based p-MTJ spin valves with [Co/Pt]n–SyAF layers ex situ annealed at 350 °C and 30 kOe for 30 min, the tunneling magneto-resistance (TMR) ratio strongly depended on the radio-frequency (RF) sputtering power in a 0.65–1.15 nm thick MgO tunneling barrier, achieving a TMR ratio of 168% at 300 W.

Sputtering Power

WO3 -incorporated C–TiO2 nanotubes were successfully fabricated using radio frequency sputtering technique. The effects of sputtering powers on the nanotube morphology, crystal structure, optical properties and visible photoresponse were investigated. Lattice substitution of WO3 species within the lattice of C–TiO2 nanotubes has an important function in maximizing the photocurrent generation. WO3 -incorporated C–TiO2 nanotubes exhibit good visible photoresponse compared with C–TiO2 nanotubes. The interpretation of interband states has an important function in improving photoinduced electron transport.
