Two Milling Time Regimes in the Evolution of Magnetic Anisotropy of Mechanically Alloyed Soft Magnetic Powders
(Elsevier, 2011)
The milling time evolution of magnetic anisotropy of ball milled powders can be described considering two regimes. First, for short milling times, the main factor affecting the magnetic behavior of the alloy is the ...

Magneto-caloric effect in the pseudo-binary intermetallic YPrFe17 compound
(Elsevier, 2011)
We have synthesized the intermetallic YPrFe17 compound by arc-melting. X-ray and neutron powder diffraction show that the crystal structure is rhombohedral with View the MathML source space group (Th2Zn17-type). The ...

Electrical properties of biomorphic SiC ceramics and SiC/Si composites fabricated from medium density fiberboard
(2011)
A study has been made of the dependences of the electrical resistivity and the Hall coefficient on the temperature in the range 1.8–1300 K and on magnetic fields of up to 28 kOe for the biomorphic SiC/Si (MDF-SiC/Si) ...

Origin of the magnetic anomaly and tunneling effect of europium on the ferromagnetic ordering in Eu8-xSrxGa16Ge30 (x = 0,4) type-I clathrates.
(American Physical Society, 2011)
Systematic dc magnetization studies using the Banerjee criterion, Kouvel-Fisher, and magnetocaloric effect methods provide physical insights into the origin of themagnetic anomaly and the tunneling effect of europium ...

Creep behavior of TiCxN1-x-CoTi cermets synthesized by mechanically induced self-sustaining reaction
(Elsevier, 2011-03)
The plastic flow of TiCxN1−x–CoTi cermets has been investigated by uniaxial compression tests carried out in argon atmosphere at temperatures between 1100 and 1200 ◦C. Two different cermets, with 5 wt.% W or WC content ...

Magnetic and Structural Characterization of Mo-Hitperm Alloys with Different Fe/Co Ratio
(Elsevier, 2011)
The influence of the Co content on the microstructure and magnetic behaviour of a series of amorphous and nanocrystalline (FeCo) 79Mo8Cu1B12 alloys is reported. Changes in the magnetic properties provoked by the microstructural ...

Tunable magnetocaloric effect in Gd-based glassy ribbons
(AIP Publishing, 2011)
The series of glassy ribbons Gd 60 M 30 In 10 ( M ¼ Mn, Co, Ni, Cu) was synthesized by melt-spinning. The change of transition element M in these Gd-based metallic glasses was proven to induce huge variations ...

Periodic forcing on the oscillatory behavior of a reaction simulated by Monte Carlo
(The Laboratory "Control of Complex Systems", 2011-09)
In this paper we study the reaction $N_{2}O + H_{2}$ catalyzed on a Ir (110) surface by Monte Carlo simulation (MC), focusing our study on the temporal evolution of the system. The phase diagram of the model, which represents ...

Procedure to use phosphogypsum industrial waste for mineral CO 2 sequestration
(Elsevier, 2011)
Industrial wet phosphoric acid production in Huelva (SW Spain) has led to the controversial stockpiling of waste phosphogypsum by-products, resulting in the release of significant quantities of toxic impurities in salt ...
