Magnetoresistance and quantum oscillations in the WTe-=SUB=-2-=/SUB=- semimetal

نویسندگان

چکیده

The discovery of extreme magnetoresistance (XMR) in non-magnetic materials attracted attention to the WTe 2 semimetal. We have carried out studies a tungsten ditelluride single crystal magnetic field range up 14 T. Magnetoresistance increased with increasing following near quadratic law without saturation. Shubnikov-de Haas oscillations were observed. Four fundamental frequencies found spectrum, which correspond two electron and hole pockets caused by strong spin-orbit coupling. Keywords: semimetal, magnetoresistance, oscillations, spectrum.

Toward the Ultimate Limit of Phase Change in Ge<sub>2</sub>Sb<sub>2</sub>Te<sub>5</sub>

The limit to which the phase change memory material Ge2Sb2Te5 can be scaled toward the smallest possible memory cell is investigated using structural and optical methodologies. The encapsulation material surrounding the Ge2Sb2Te5 has an increasingly dominant effect on the material’s ability to change phase, and a profound increase in the crystallization temperature is observed when the Ge2Sb2Te...

Synthesis and Characterization of Tb[N(CN)<sub>2</sub>]<sub>3</sub>·2H<sub>2</sub>O and Eu[N(CN)<sub>2</sub>]<sub>3</sub>·2H<sub>2</sub>O: Two New Luminescent Rare-Earth Dicyanamides

Two new rare-earth dicyanamides, namely, Tb[N(CN)2]3‚2H2O and Eu[N(CN)2]3‚2H2O, have been prepared by ion exchange in aqueous solution, followed by evaporation of the solvent at room temperature. The structures of both compounds have been solved and refined from single-crystal and powder X-ray diffraction data, respectively. The two compounds are isostructural and are built up from irregular qu...

Magnetic properties of the Haldane-gap material [Ni(C<sub>2</sub>H<sub>8</sub>N<sub>2</sub>)<sub>2</sub>NO<sub>2</sub>](BF<sub>4</sub>)

Results of magnetization and high-field electron spin resonance (ESR) studies of the new spin-1 Haldane-chain material [Ni(C2H8N2)2NO2] (BF4) (NENB) are reported. A definite signature of the Haldane state in NENB was obtained. From the analysis of the frequency–field dependence of magnetic excitations in NENB, the spin-Hamiltonian parameters were calculated, yielding 1/kB = 17.4 K, g‖ = 2.14, D...
