Abstract: The discovery of extreme magnetoresistance (MR) in nonmagnetic materials attracted attention to WTe ₂ 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.
