Tb/Co MULTILAYER FILMS AND THE RELAXATION OF THEIR INTERFACE
نویسندگان
چکیده
In Tb/Co multilayers, the saturation magnetization M, and the anisotropy constant K,, as a function of the modulation period are fitted by a mean-field model and a dipolar interaction model respectively. The Kerr rotation angles Bk relax at room temperature, which could be attributed to the existence of shear stress due to lattice mismatch at the interface.

X-ray diffraction measurements were performed on Co?Pt1-?/Pd, Co/Pd, Co/Fe, and Co/W multilayer samples with different structures, such as Co?Pt1-? alloy layer composition ?, bilayer thickness, and number of bilayers. Multilayer samples were made by magnetron sputtering in a chamber with multi-parallel guns and a position controllable substrate. Co?Pt1-? alloy layers were deposited by cosputter...
متن کاملANISOTROPY AND MAGNETO-OPTICAL PROPERTIES OF SPUTTERED Co/Ni MULTILAYER THIN FILMS
AbsrraclSeveral series of sputtered Co/Ni multilayer thin films have been investigated. The volume and interface contributions to the magnetic anisotropy were determined from magnetization measurements, and the interface anisotropy, 6 = 0.23 f 0.03 erg/cm2, was found to support perpendicular magnetic anisotropy. The anisotropy constant, K, increased with the Au buffer layer thickness, indicatin...
متن کاملAdsorption of Au and Pd Atoms on Thin SiO2 Films: the Role of Atomic Structure
The low-temperature deposition of Au and Pd atoms on thin SiO2 films grown on Mo(112) has been studied by scanning tunneling microscopy (STM), infrared reflection absorption spectroscopy, and CO adsorption. On the monolayer films, gold forms three-dimensional nanoparticles at temperatures as low as 10 K and does not affect the phonon spectra of the silica films. On the other hand, palladium exh...
متن کاملMultilayer Nano Films for Corrosion Control
Nano films consisting of an alternating sequence of positively and negatively charged polyelectrolytes have been prepared by means of the electrostatic layer-by-layer (LBL) sequential assembly technique on treated and untreated mild steel wires. Inhibitor was encapsulated between cationic and anionic polyelectrolyte nano films. This paper mainly focuses on the effect of these nano-films of poly...
متن کاملEnhancement of MD-55-2 radiochromic film sensitivity using a multilayer film technique for applications in the low dose range
ABSTRACTBackgrounds: MD-55-2 is one of the Radiochromic film models with the sensitivity suitable for dose measurements ranging from 5 to 100 Gy. However, this lower limit makes the film impractical for its applications in many areas such as brachytherapy source dosimetry.Materials and methods: In this project, the useful range of the film has been extended by using a multilayer film techniqu...
