Study on Co∕Pt Multilayer with Isothermal Annealing

AIP Conference Proceedings, 2011
Co/Pt multilayer system has been grown using Ion beam sputtering process. The multilayer system has been vacuum annealed at various temperatures. The structural and magnetic properties have been investigated by using X‐ray reflectivity, X‐ray diffraction and magneto optical Kerr effect. It has been observed that thermal annealing results in the partial

Isochronal and Isothermal Annealing of Wrought Aluminum Alloy

Defect and Diffusion Forum, 2011
Positron annihilation lifetime (PAL) is one of the most important nuclear techniques used in material science. Electrical measurements are also used in material science. Samples of 25 % deformation have been used for these studies. Both positron annihilation lifetime and electrical measurements were used to determined the activation energy of migration

Langmuir Isotherms of Quenched and Annealed Polyelectrolyte Brushes

Langmuir, 2000
We report here Langmuir isotherms of diblock copolymers containing a short neutral hydrophobic sequence (polystyrene) and a long water-soluble polyelectrolyte sequence (polyvinyl-2-pyridine). This study focuses on the polyelectrolyte sequence, which is a weak polyelectrolyte when unmodified and strong polyelectrolyte when quaternized.

Deformation and isothermal annealing behaviour of nickel

British Journal of Applied Physics, 1967
Isothermal annealing of cold-worked nickel produces softening which initially occurs exponentially but which is followed by a sigmoidal stage. A theory of isothermal softening behaviour, based upon polygonization of subgrains, is presented.

Isothermal Annealing of Space Charge in MNOS Structures

physica status solidi (a), 1986
The influence of X-ray irradiation on the stationary conductivity and isothermal depolarization of MNOS structures is studied. It is shown that low-temperature annealing of radiated MNOS structures without bias voltage increases activation energy under isothermal depolarization from EA = 0.8 eV up to EA = 1.4 eV.

Isothermal annealing of oxygen decorated defects in silver

Hyperfine Interactions, 1983
The dynamics of trapping and detrapping processes of oxygen decorated radiation defects in silver were investigated by the TDPAC technique. Three defect clusters containing In, oxygen and vacancies were studied by isothermal annelaing experiments between 250°C and 450°C.

Phase Formation in Isothermally Annealed (Co0.95Fe0.05)89Zr7B4 Nanocrystalline Alloys

Metallurgical and Materials Transactions A, 2007
This report focuses on the phase relations and transformations in a (Fe0.05Co0.95)89Zr7B4 melt-spun alloy with an emphasis on crystallization and its effects on thermomagnetic properties. When as-spun ribbons are annealed at relatively low temperatures (near primary crystallization), the nucleation and growth of nonequilibrium body-centered-cubic (bcc)

Isothermal Annealing in P⁺ Ion-Implanted Silicon

Journal of the Physical Society of Japan, 1975
The behaviors on isothermal annealing of paramagnetic centers produced by P + ion implantation into Si (ion energies: 50 and 100 keV; ion doses: 1×10 15 and 2×10 14 cm -2 ) and those obtained for Si surface are investigated by ESR measurements. A new method different from the conventional Bemski method is used to obtain the activation energy (Δ E ) for

Hydrogen isotherms for annealed, un-activated LaNi5 (273–333K)

Journal of Alloys and Compounds, 2013
Abstract Hydrogen absorption isotherms (273–333 K) have been measured for closely stoichiometric, annealed, un-activated LaNi5, i.e., a virgin un-activated LaNi5 sample was employed at each temperature. This is the first time that such isotherms have been measured for annealed, un-activated LaNi5 at such low temperatures ⩽298 K.

Crystallization behaviour of Al85Y10Ni5 by isochronal and isothermal annealing

Acta Metallurgica et Materialia, 1991
Abstract Crystallization of Al 85 Y 10 Ni 5 by isochronal annealing showed a strong dependence on scan rate over the range of 0.9–20.7 K/min. At a scan rate of 0.9 K/min, crystallization of Al 85 Y 10 Ni 5 occurred by primary crystallization in a single step.
