摘要：

We report detailed study of angular-dependent magnetoresistance (AMR) with tilting angle theta from c axis ranging from 0 degrees to 360 degrees on a high-quality FeSe single crystal. A pronounced AMR with twofold symmetry is observed, which is caused by the quasi-two-dimensional (quasi-2D) Fermi surface. The pronounced AMR is observed only in the orthorhombic phase, indicating that the quasi-2D Fermi surface is induced by the structural transition. Details about the influence of the multiband effect to the AMR are also discussed. Besides, the angular response of a possible Dirac-cone-like band structure is investigated by analyzing the detailed magnetoresistance at different theta. The obtained characteristic field (B*) can be also roughly scaled in the 2D approximation, which indicates that the Dirac-cone-like state is also 2D in nature.
