Magnetic and structural aspects of the annealing-induced transformation of rapidly-solidified Mn55Al45 ribbons from the as-quenched metastable antiferromagnetic (AF) ε-phase to the target ferromagnetic (FM) L10 τ-phase are investigated. The as-solidified material exhibits a majority hexagonal ε-MnAl phase revealing a large exchange bias shift below a magnetic blocking temperature TB~95 K (Hex~1...

Infrared reflection absorption spectroscopy (IRAS) was used to study the adsorption of carbon monoxide on mixed S and Co overlayers on a Mo(l10) surface. The results of this study indicate that there is a migration/ segregation of the adatoms into 2-D and 3-D islands and that the different domains are distinguishable by the stretching frequency of the adsorbed CO. Clean Mo(l10) as well as sulfi...

Atomic and continuum effects in L10 magnets are investigated. Emphasis is on the competition between ferromagnetism, antiferromagnetism, and noncollinear order in both perfect and imperfect structures, and on the temperature dependence of the magnetic anisotropy. The applicability of micromagnetic and atomistic approaches depends on the length scales involved, but there is a broad range of phen...

With indivisible shareholdings and simultaneous shareholder decisionmaking, the existing takeover literature provides a reasonable pro…t only in asymmetric equilibria. We allow the raider to approach shareholders sequentially and thereby …nd a unique equilibrium that produces the same outcome. J.E.L. classi…cation: L10, G34, H41.

It is shown that the implementation of the Large–Nc approximation helps to get insight into the structure of, in principle, any QCD-like theory. As an example, we will compute the NLO corrections to L10 in the chiral limit with a Lagrangian with Resonances.

The polytwinned structure in L10 FePd alloy is studied by using both conventional TEM and Lorentz microscopy methods. Herein we develop a trace analysis method to determine the surface orientation of a magnetic domain image without the use of electron diffraction patterns. This allows us to analyze magnetization directions. 2002 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights...

We have used modification of specific amino acid residues in the E. coli ribosomal protein LIO as a tool to study its interactions with another ribosomal protein, L7/L12, as well as with ribosomal core particles and with 23S RNA. The ribosome and RNA binding capability of LIO was found to be inhibited by modification of one more more of its arginine residues. This treatment does not affect the ...

We have used identified neurons from the abdominal ganglion of the mollusc Aplysia to construct and analyze two circuits in vitro. Each of these circuits was capable of producing two patterns of persistent activity; that is, they had bistable output states. The output could be switched between the stable states by a brief, external input. One circuit consisted of cocultured L10 and left upper q...

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting galley proof before it is published in its final citable form. Please note that during the production process errors may be discovered which coul...
