Microstructure of BaM Thin fIlms Deposited on (111) Oriented ZnFe2O4 Underlayer.

Microstructure of the Cr underlayer and its effect on Sm-Co//Cr thin films

Growth of CoCrTa„112̄0...-oriented thin films on a D03 Mn3Si„002... underlayer

Mn3Si possesses a D03 structure, which is a bcc derivative structure with nearly the same atomic spacing as Cr and NiAl which have been commonly used for longitudinal magnetic recording underlayers. AG~30 nm!/CoCrTa~40 nm!/Mn3Si(x , x5100, 200, 400 nm)/Ag~75 nm! thin films were sputter deposited onto hydrofluoric acid ~HF!-etched Si:~001! substrates at elevated temperature. Compared to the 100 ...

Enhanced methanol sensing performance of oblique deposited WO3 thin films

Methanol (CH3OH) is a colorless liquid with a mild odor. The wide ranges of applications, toxicity and clinical implications of methanol have made necessary to develop reliable and high-performance methanol sensors. In this paper, WO3 thin films were deposited on SiO2/Si substrates by e-beam evaporation technique under normal and oblique angles and then post-annealed at 500 °C with a flow of ox...

Preferentially oriented BaTiO3 thin films deposited on silicon with thin intermediate buffer layers

Barium titanate (BaTiO3) thin films are prepared by conventional 2-methoxy ethanol-based chemical solution deposition. We report highly c-axis-oriented BaTiO3 thin films grown on silicon substrates, coated with a lanthanum oxynitrate buffer layer of 8.9 nm. The influence of the intermediate buffer layer on the crystallization of BaTiO3 film is investigated. The annealing temperature and buffer ...

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...
