In this research, the nickel oxide was dissolved in cryolite at temperatures of 880, 940 and 1000°C. In order to reduce the nickel oxide, aluminum was added to the salt. Simultaneously the nickel oxide was reduced and Al3Ni2 intermetallic compound was formed. In the duration intervals of 2.5-40 minutes samples of the salt and metallic phases were taken. The variation of the nickel content in me...

Electrical and magnetic properties of CeCuGe were investigated through electrical resistivity, thermal conductivity and magnetization measurements in the temperature range 2–300 K. Magnetization measurements indicate a paramagnetic to ferromagnetic transition at TZ10 K, in agreement with previous work. There are two distinct paramagnetic regimes: At high-T the magnetic moment per cerium is 2.50...

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...

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 ...

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...

We report on a comprehensive study of the magnetic properties of YbCo2Si2 investigated using a single crystal. All data confirm a stable trivalent Yb state carrying a well-localized 4f moment, as well as a non-magnetic Co state. We observed a sizeable anisotropy in the magnetic susceptibility χ(T ), with the moment in the basal plane twice as large as that along the c-direction. Combining this ...

Plasma Transferred Arc hardfacing (PTA) is an excellent tool for surface tailoring as it allows for the manipulation of coatings chemical composition. In particular in-situ alloy development can be achieved during the deposition of different powder mixtures. In this work powder mixtures of Ni-Al, Nb-Al and Fe-Al were deposited by PTA. Coatings were characterized for their mechanical features at...

The equiatomic rare earth compounds REPtZn (RE = Y, Pr, Nd, Gd–Tm) were synthesized from the elements in sealed tantalum tubes by high-frequency melting at 1500 K followed by annealing at 1120 K and quenching. The samples were characterized by powder X-ray diffraction. The structures of four crystals were refined from single-crystal diffractometer data: TiNiSi type, Pnma, a = 707.1(1), b = 430....

based on the crystal and magnetic structural properties of some gd intermetallic compounds, it is shown that with increasing conduction electron concentration, gd experiences electronic and magnetic instability, and that these behaviors point to the appearance of kondo lattice. we suggest that the conduction electrons have gained local character. it is shown that kondo effect should be observed...
