چکیده

CoCrPtTa/Ti bilayer thin films have been sputter deposited onto both glass and Al substrates under high sputtering rate in a manufacturing environment. From microstructure and magnetic property studies, it is found that Cr segregation and stacking fault density are the two major issues in obtaining high quality perpendicular media. (0002) texture orientation spread and lattice parameter remain almost constant within the variation range of the deposition parameters, though there is a small distinction between the media on glass and those on Al substrates.

Investigation of the electrical properties and corrosion resistance of TiN coating deposited by reactive sputtering on the titanium bipolar plate, used in polymeric fuel cell

The effect of titanium nitride film on the properties of titanium bipolar plates used in polymeric fuel cell was investigated in this research. TiN coatings was deposited on the Ti-grade 1 substrate by using DC-sputtering method. Pure titanium was used as target and coating deposition was done in argon and nitrogen atmosphere. Different TiN thickness was developed by changing sputtering time. T...

CRYSTAL STRUCTURE AND OPTICAL PROPERTIES OF TiO2 THIN FILMS PREPARED BY REACTIVE RF MAGNETRON SPUTTERING CHARAKTERYSTYKA CIENKICH WARSTW TiO2 OTRZYMANYCH METODĄ REAKTYWNEGO ROZPYLANIA

In sputtering deposition process of TiO2, metal Ti or sintered TiO2 target is used as deposition source. In this study, we have compared the characteristic of target materials. When TiO2 target was used, stoichiometric TiO2 films was deposited under the Ar atmosphere containing 1.0% of oxygen. The highest sputtering rate under this atmosphere was 3.9nm/min at 3.4W/cm2. But, sintered TiO2 target...

Perpendicular Magnetic Anisotropy in Ion Beam

Co/Ni multilayers display perpendicular magnetic anisotropy and have applications in magnetic devices that could lead to a large increase in the density of magnetic storage. Co/Ni 10-(2 A Co/ 8A Ni) and 10-(2 A Co/ 4A Ni) multilayers were deposited with ion beam sputtering on either ion beam sputtered copper or direct current magnetron sputtered gold buffer layers of various thicknesses. The ef...

Microstructure and magnetic properties of very" thin CoCr films deposited on different underlayers by if-sputtering

Very thin CoCr films deposited on different underlayers on glass disk substrates were studied by the magneto-optic Kerr effect, VSM, torque magnetometcy and TEM selected area diffraction. Square or near square perpendicular loops were obtained from Co/Ti , CoCr/Au: CoCr/AI, CoCr/C and CoCr/Si films. TEM SAD study revealed that the crystalline structure is a key factor determining the magnetic a...

High-power impulse magnetron sputtering of Ti-Si-C thin films from a Ti3SiC2 compound target

We have deposited Ti-Si-C thin films using high-power impulse magnetron sputtering (HIPIMS) from a Ti3SiC2 compound target. The as-deposited films were composite materials with TiC as the main crystalline constituent. X-ray diffraction and photoelectron spectroscopy indicated that they also contained amorphous SiC, and for films deposited on inclined substrates, crystalline Ti5Si3Cx. The film m...
