We studied magnetic anisotropic properties, interlayer coupling, and spin wave relaxation in ten periods of CoFeB/Cr/CoFeB films grown on seed layers of Cu with a Co:Fe:B composition ratio of 2:2:1. The measurements were taken in samples with 50 Å layers of CoFeB using the ferromagnetic resonance technique. The thickness of the Cr interlayers was varied(More)
An array of transfer length mode (TLM) structures were designed and made on electrically isolated phosphourous -doped hydrogenated amorphous silicon (a-Si:H) thin films. Annealing effects on NiCr/a-Si:H contacts in the temperature rang from 100 °C to 400°C were studied. Electrical measurements were performed to characterize the interaction of(More)
The structure and properties of thin films obtained by radio frequency (RF) plasma-enhanced chemical vapor deposition (PECVD) through decomposition of silane mixed with argon have been studied by Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, ultraviolet and visible (UV-vis) spectroscopy and transmission electron microscope (TEM),(More)
The structure of hydrogenated amorphous silicon (a-Si:H) thin films embedded with nano-crystal grains deposited by conventional radio frequency (RF) plasma enhanced chemical vapor deposition (PECVD) through decomposition of silane diluted with argon has been studied by X-ray diffraction (XRD), Fourier transform infrared (FTIR) and Raman spectroscopy. It is(More)
