Elastic Properties of Intermetallic Compounds.

Hydrogen storage properties of Ml, _,Ca,Ni, pseudobinary intermetallic compounds

The hydrogen storage properties of the pseudobinary intermetallic compounds Ml, -.Ca,Ni, (where Ml is La-rich mischmetal and x varies from 0 to 0.9) were investigated over the temperature range of 25-80°C It was found in experiment that with increasing x in Ml,_,Ca,Ni, the incubation time for its first hydrogenation shortened, the first hydrogen absorption rate accelerated, the hysteresis lower...

Hydrogen in R2Fe17 intermetallic compounds: Structural, thermodynamic, and magnetic properties

Prediction of stable insulating intermetallic compounds

We explore the stability of structure exhibiting hybridization gaps across a broad range of binary and ternary intermetallic compositions by means of band structure and total energy calculations. This search reveals previously unknown metal-based insulators, some with large gaps exceeding 1 eV, such as Al2Fe and Al4IrRe. We confirm large gaps using a hybrid density functional including exact ex...

Driving magnetostructural transitions in layered intermetallic compounds.

We report the dramatic effect of applied pressure and magnetic field on the layered intermetallic compound Pr(0.5)Y(0.5)Mn(2)Ge(2). In the absence of pressure or magnetic field this compound displays interplanar ferromagnetism at room temperature and undergoes an isostructural first order magnetic transition (FOMT) to an antiferromagnetic state below 158 K, followed by another FOMT at 50 K due ...

Quadrupole Interactions in Rare-earth Intermetallic Compounds

A survey of the role played by the one-ion magnetoelastic and two-ion quadrupolar interactions on the magnetic and elastic properties of the rare-earth intermetallic compounds is given. These couplings are present in numerous systems and manifest themselves through a great variety of effects. The study of the multipolar interactions concerning the 4f shell has known a great development about ra...
