摘要：

The discovery of extreme magnetoresistance (MR) in nonmagnetic materials attracted attention to WTe2 semimetal. We studied MR in a single crystal of tungsten ditelluride in the range of magnetic fields up to 14 T. MR increased with increasing field following a close-to-quadratic law without saturation. The Shubnikov-de Haas oscillations were observed. Four fundamental frequencies were found in the oscillation spectrum, which correspond to two electron and two hole pockets, caused by strong spin-orbit coupling.
