C-axis oriented Ba-ferrite thin film with small grain for perpendicular magnetic recording

Hexagonal Ba-ferrite(BaM) thin films with amorphous AlO(a-AlO) under-layer were prepared by a facing targets sputtering system. The grain size of c-axis perpendicularly oriented BaM/a-AlO films is about 20 nm at the thickness of 20 nm for BaM layer. The perpendicular coercivity is about 3.5-4.3 kOe with BaM layer thickness in the range from 80 to 30 nm and 2.3 kOe for BaM layer thickness of 20 nm.The in-plane coercivity for BaM/a-AlO films was less than 0. 1 kOe at the thickness ranging from 20 to 80 nm.

Reactivities of spin-orbit states in Al((2)P(1/2,3/2))+O2(X(3)Σ(-)(g))AlO(X(2)Σ(+))+O((3)P(0,1,2)). A fluorescence imaging study

A crossed beam chemical reaction, Al((2)P(1/2,3/2))+O2(X(3)Σ(-)(g)) AlO(X(2)Σ(+))+O((3)P(0,1,2)) was investigated by fluorescence imaging techniques. Multiplex detection of speeds and quantum states of both reactants and products has been implemented. The

High-contrast top-emitting organic light-emitting diodes with AlO1.086 dark-and-conductive electrodes

To improve the poor contrast of conventional organic light-emitting diodes (OLEDs) resulting from highly reflective metal electrode, a dark-and-conductive electrode with an average reflectance of 28.1% and a resistivity of 4.6 × 10-4 Ω/cm was fabricated by fine-tuning O2/Ar flow ratio on aluminum electrode sputtering. X-ray photoelectron spectroscopy analysis indicates pure aluminum and aluminum oxide coexist in the fabricated dark-and-conductive electrodes. With the proposed dark-and-conductive AlO1.086 electrodes, top-emitting OLEDs exhibit significantly improved contrast, whereas maintain moderate luminous efficiency. The demonstrated AlO1.086 dark-and-conductive electrodes can potentially replace the circular polarizers for high-contrast OLED display applications.

Electronic transition moment of the AlO(B(2)Σ(+)-X(2)Σ(+)) emission. Analysis of the R dependence of the Al(2+)O(2-) character in the X(2)Σ(+) state

The dependence of the electronic transition moment, R(e)(R), of the AlO(B(2)Σ(+)-X(2)Σ(+)) system on the internuclear distance, R, has been determined by an analysis of the intensity distribution of the emission spectra as R(e)(R)=[1-2.29(13)(R/?-1.5)**2]

Kinetics of the Reaction Al(2PO) + H2O over an Extended Temperature Range

The temperature dependence of the reaction Al(2PK0) + H2O has been investigated over the temperature range 298-1174 K.Aluminium atoms were produced by photodissociation of Al(C2H5)3 and were detected by laser-induced fluorescence.Non

MICROSTRUCTURE DEVELOPMENT OF ALUMINUM OXIDE - GRAPHITE MIXTURE DURING CARBOTHERMIC REDUCTION.

Reactions in the system Al-O-C are discussed. The development of the unique composite microstructure is attributed to reactions which serve to coarsen internal grains by vapor-phase transport of volatile aluminum suboxides and, thereby, reduce firing shri

Reaction dynamics of Al+O2→AlO+O studied by the crossed-beam laser-induced fluorescence technique

A study was performed on the reaction dynamics of Al+O 2→AlO+O. The crossed-beam technique at five collision energies from 6.9 to 25.3 kJ/mol was used for the purpose. The laser-induced fluorescence technique was used for the detection of product AlO. The determination of the rotational-vibrational distributions was also discussed.

Formation and Oxidation of Metal-Based CO and CO2 Complexes: Characterization of Al(CO)x and Al(CO2)x and their Oxidation

In a comparative study, aluminum atoms entrained in argon, CO, and CO2 are oxidized with ozone to inspect the nature of aluminum complexation with CO and CO2 to form Al(CO)x (x= 1, 2) and AlCO2 adducts.The optical signatures corresponding to the chemiluminescent oxidation of these complexes with ozone to form the AlO B2Σ+ state or, in the case of CO2, a polyatomic complex are compared to that AlO B2Σ+ emission associated with the chemiluminescent oxidation of nonbonded aluminum atoms in argon.We (1) establish a method for evaluating M(CO)x binding energies and (2) observe the optical signature for a potentially long-lived (ca. 1E-7 s) metal oxide-carbon dioxide solvation complex formed in metal-CO2 complex oxidation.From a comparison of these studies, with results obtained for Al-N2O oxidation, we estimate a lower bound to the total (Al(CO)2 binding energy (to Al+2CO) of ca.0.7 eV.The current study in conjunction with parallel efforts involving the transition metals suggests a method for studying the spectra of MCO, M(CO)2, and M-CO2 complexes.

Oxidation of Transition-Metal Cations in the Gas Phase. Oxigen Bond Dissociation Energies and Formation of an Excited-State Product

Gas-phase studies of oxigen atom transfer fro various oxidants to transition-metal cations by ion cyclotron resonance spectroscopy are reported.Observation of these reactions is used to establish upper and lower limits for metal oxide-cation bond dissociation energies, D(M+-O).For MgO+, AlO+, MnO+, CoO+, NiO+, CuO+, and ZnO+ the results bracket D(M+-O) between D(O2-O)=25.5 kcal/mol and D(N2-O)=40.0 kcal/mol.For V+ and Fe+ the results also bracket the bond energy in relatively narrow ranges: D(V+-O)=135+/-16 kcal/mol and D(Fe+-O)=101+/-18 kcal/mol.New upper and/or lower limits are established for some of the other metal cation studied.The VO+ produced by reaction of V+ with N2O reacts with H2 or CH4 to give VOH+.However, when VO+ is produced by reaction of V+ with O2, D(O-O)=119.2 kcal/mol, reaction to give VOH+ does not occur.These results suggest that the VO+ product of the reaction of V+ and N2O is an excited-state species with a lifetime at least as long as the reaction time which is as long as about 150 ms in these experiments.Similar behavior is seen with TiO+.
