SYNTHESIS OF Bi-Zn-Al-B-Si-O NANO-GLASS FOR MULTILAYER CHIP INDUCTORS
Modern Physics Letters B, 2009The ferrite added with Bi - Zn - Al - B - Si - O nano-glass was sintered at 840-900°C, 2 h and the initial permeability, quality factor, density and saturation magnetization of the samples were measured. The initial permeability of the nano-glass added sample was about 62.6 at 0.1 wt%, and showed a sharp increase from 0.4 to 0.5 wt%.

dHvA MEASUREMENTS ON La1-xCexMIn5 WHERE M=Rh, Ir AND Co
Physical Phenomena at High Magnetic Fields IV, 2002Measurements of the de Haas-van Alphen effect in Ce x La 1-x MIn 5 show that x dependence for the three different value of M behaves quite differently. The Ce 4f electrons remain localized and have little interaction for all x in the Rh alloys, but strongly interact with the conduction electrons in both the Ir and Co alloys. Both the dependence on

Second hyperpolarizability of multimetallocenes [Cp–Mn–Cp] of Be, Mg and Ca
Journal of Theoretical and Computational Chemistry, 2015Multimetallocene complexes ( Cp – M n– Cp ) of Be , Mg and Ca have been considered for the theoretical study of static second hyperpolarizability using a number of DFT functionals. Owing to the cooperative effect in bonding, beryllium forms multiberyllocene complexes ( Cp – Be n– Cp ) which have sufficient thermal stability with respect to ...

The structural, electronic and magnetic properties of MnXY ( X = Ru , Rh and Y = Ga , Ge , Sb ) Heusler alloys are studied using density functional theory by the WIEN2k package. These materials are ferromagnetic. Also they have some interesting half-metallic properties.

MAGNETIC PROPERTIES AND CRYSTAL STRUCTURE OF MELT SPUN Sm(Co, M)7 RIBBONS (M = Hf, V, Nb, andTa)
Modern Physics Letters B, 2009Magnetic properties and crystal structure of melt spun SmCo 7-x M x ( M = Hf , V , Nb , and Ta ; x = 0–0.3) ribbons have been investigated. The experimental results showed that not just Hf but also V , Nb and Ta prefer to occupy 2e site in the TbCu 7 structure and remarkably increase coercivity of the ribbons from 1.7 kOe for x = 0 to 10–12 kOe for x =

t+t clustering in He isotopes is investigated by using two theoretical approaches. A role of the t+t cluster component in the ground state is examined with AMD triple-S, allowing the wider configuration space containing simultaneously the "t+t+valence neutrons" structure and "4 He +valence neutrons" structure. We understand the importance of the t + t

COMPUTATIONAL STUDY OF TERNARY ALLOY NANOCLUSTER COMPOSITIONAL STRUCTURES: Ni–Cu–Rh VERSUS Ni–Cu–Pd
International Journal of Nanoscience, 2004The Free-energy Concentration Expansion Method (FCEM) was utilized for the prediction of compositional structures in Ni – Cu – Rh cubo-octahedron nanoclusters in comparison to recently reported Ni – Cu – Pd data. While both systems exhibit site-specific, sequentially competitive surface segregation (and resultant core separations), remarkable ...

STRUCTURE AND MAGNETIC PROPERTIES OF Co12X(X = Ni, Ag, Pt, Au) CLUSTERS
International Journal of Modern Physics B, 2007The ground state structures of Co 12 X ( X = Ni , Ag , Pt , Au ) clusters are obtained by a genetic algorithm with a Gupta-like many-body potential, and further optimized using the density functional theory with generalized gradient approximation. The structures of Co 12 X have a slightly distorted icosahedral pattern. The X atom is on the surface for

The effects of Hf substitution and C content on the magnetic properties, phase evolution, and microstructure of melt spun ( Sm , Pr ) Co 7- x Hf x C y ( x = 0-0.5; y = 0-0.14) ribbons have been studied. A proper Hf substitution is helpful not only in stabilizing 1:7 phase but also in enhancing its magnetic anisotropy field.

ELASTIC MODULI FOR THREE SUPERCONDUCTING PHASES OF Bi-Sr-Ca-Cu-O
Modern Physics Letters B, 1992We have measured the absolute values of longitudinal and transversal sound velocities in ceramic samples of Bi 2 Sr 2 Ca n-1 Cu n O 2n+4 (n=1, 2,3). We have compared various methods of calculation of "true" elastic moduli of matrix material. We used best of them to find the elastic moduli, sound velocities and Debye temperatures of the material.
