X-ray study of the ordering phase transition at the Cu3Au (111) surface
… the phase transition at the (111) surface of Cu3Au by glancing incidence x-ray scattering. The experiment was designed to approach the general question of surface behavior near a bulk first order phase transition. We have studied three aspects of the phase transition: the surface order …

Studies of ordering on surfaces and in superlattices by molecular beam epitaxy
… probe of the kinetics by which a surface of Cu3Au re-orders of was developed. By growing a disordered layer onto a well ordered surface, the kinetics of ordering in layers of almost arbitrarily small thickness can be studied. By eliminating the need to quench the sample this procedure removes …

Disorder and nanopatterning in ordered binary alloys: in situ ion irradiation and kinetic Monte Carlo simulation
… and simulated binary alloys. The behavior of Cu3Au, an alloy with L12 chemical order, is investigated experimentally through in situ electron diffraction and dark-field transmission electron microscopy. Under irradiation with 500 keV Ne+ ions, our diffraction analysis reveals a similar, but …

Applications of lattice dynamics theory : calculating vibrational entropy in alloys and dielectric losses in ceramics
… ordered-L12 and disordered phases in the Au3Cu, Cu3Au, Cu3Pd, Pd3Cu, Cu3Pt, Au3Pd, and Pd3Au systems are calculated. This study was done using first-principles energy calculations and the supercell method. Calculated values of ASÊ»rder-disorder ranged between -0.05 - 0.07 kB. Length-dependent …

Epitaxial Niobium (011) Surfaces as a Template for Cu(3)Au
Cu3Au films are grown under a number of conditions, which isolates step nucleation as the key to the stacking bias. The stacking ratio has a sinusoidal dependance on miscut azimuth. The ratio depends on miscut magnitude first linearly but with a rapid increase for miscuts; near 1°. This …

Existenzbereiche und physikalische Eigenschaften metallreicher Perowskite (SE3X)M (SE = Seltenerd-Metall; X = N, O; M = Al, Ga, In, Sn)
… Pulvern charakterisiert. Das in der Literatur im Cu3Au-Strukturtyp beschrieben kubische Polymorph von Ce3Al wurde auf einen ternären metallreichen Perowskit (Ce3X)Al zurückgeführt.

Untersuchung der Oberflaechensegregation geordneter Legierungen mittels Ionenstreuung am Beispiel CuAu(100)
… Kompositionen, naemlich CuAu3 und insbesondere Cu3Au sind auch hinsichtlich ihres Verhaltens an der Oberflaeche eingehend untersucht. Fuer CuAu findet man wenig Information. Es zeigt sich, daß die Analyse der zweiten Atomlage von besonderem Interesse ist. Hier unterscheiden sich (mit Ausnahme von …
