Magnetotransport properties of FeSe in fields up to 50T

Abstract

Magnetotransport properties of the high-quality FeSe crystal, measured in a wide temperature range and in magnetic fields up to 50 T, show the symmetry of the main holelike and electronlike bands in this compound. In addition to the main two bands, there is also a tiny, highly mobile, electronlike band which is responsible for the non-linear behavior of ${\rho }_{xy}$(B) at low temperatures and some other peculiarities of FeSe. We observe the inversion of the ${\rho }_{xx}$ temperature coeficient at a magnetic field higher than about 20 T which is an implicit conformation of the electron-hole symmetry in the main bands.
