The finite-temperature magnetism of Ni and permalloy in body-centered-cubic bcc and face-centered-cubic fcc phases is studied theoretically using ab initio supercell calculations and Green’s function methods. The results confirm and explain the general experimental trend that the fcc phases have higher Curie temperatures than the bcc counterparts. In addition, the spin-wave stiffness constants ...

The partial occupation numbers and density of states (DOS), and the total DOS at the Fermi level are calculated as a function of reduced atomic volume for bcc and fcc alkali metals employing the linearmuffin-tin-orbital (LMTO) method. By means of the abrupt changes obtained in the partial and total DOS values at the Fermi level, good agreement with regard to experiment were found in predicting ...

This paper shows that, contrary to their favourable effect in the EU non-FCC (Former Communist Countries), fiscal rules do not significantly affect performance group of FCC. finding, which may echo differences between FCC and other inherited from Cold War period, is robust when considering various estimation methods, dividing along dimensions, using several observed computed measures performanc...

Structures of carbon supported Pt-Ru catalyst in a polymer-electrolyte-fuel-cell (PEFC) were analyzed by X-ray diffraction (XRD) and X-ray absorption spectroscopy (XAFS). XRD analysis identified a face-centered-cubic (fcc) alloy structure for Pt-Ru. XAFS analysis revealed that Pt and Ru atoms were, however, not randomly distributed in the Pt-Ru fcc lattice. A Pt atom was more likely surrounded ...

In UWB systems three factors have to be considered to design a radio link: (i) peakand (ii) average power limits defined by FCC Regulations and (iii) low supply voltage available in handheld cheap devices. An exact mathematical model for the interpretation of FCC Regulations is derived. The radio coverage of UWB networking devices is determined and a chaos-based approach for the coverage extens...

A quasi-sd4 hybridization state for group VIIIB and IB face-centered cubic (FCC) transition metals in low-dimensional nanostructures is identified, in contrast to the sd5 hybridization state in bulk. For Au, a novel three-shelled nanowire is designed with a hexagonal close-packed core in the sd5 hybridization, wrapped by FCC-(111) shell that adopts the quasi-sd4 hybridization. This new nanostru...

We trace with high numerical accuracy the phase diagram of the Gaussian-core model, a classical system of point particles interacting via a Gaussian-shaped, purely repulsive potential. This model, which provides a reliable qualitative description of the thermal behavior of interpenetrable globular polymers, is known to exhibit a polymorphic fcc-bcc transition at low densities and reentrant melt...

This study investigated the psychoanalytic hypothesis that intensity of the female castration complex (FCC) is greater in women with a masculine social role than in those with a feminine social role. Ss were normal, collegeeducated women, ages 30-55, divided into 2 groups: 26 career women (CW), unmarried, and in masculine occupations; and 25 homemakers, married, with 2 or more children, and not...
