Magnetoresistance and Quantum Oscillations in WTe2 Semimetal

Physics of the Solid State - The discovery of extreme magnetoresistance (MR) in nonmagnetic materials attracted attention to WTe2 semimetal. We studied MR in a single crystal of tungsten...     

Thermal and Magnetic Properties of Maghemite γ-Fe<Subscript>2</Subscript>O<Subscript>3</Subscript> Synthesized by a Precursor Method

Low-dimension ferromagnetic maghemite γ-Fe₂O₃ was synthesized through a precursor route, using basic iron formate Fe(OH)(HCOO)₂ as a precursor. Conditions of formation of γ-Fe₂O₃ and the temperature range of its existence on heating in air were determined. The saturation magnetization of γ-Fe₂O₃ produced through heating the precursor at 350°C 57.5 (T = 4.2 K) and 43.8 emu/g (T = 300 K).     

NMR Investigation of the WTe2 Weyl Semimetal below the Topological Transition Temperature

Physics of the Solid State - NMR investigations are performed on 125Te nuclei of WTe2 Weyl topological semimetal at temperatures of 41 and 293 K. The measurements were carried out using a Bruker...
