The angle-dependent magnetoresistance oscillation (AMRO) and Shubnikov-de Haas oscillation are investigated in the layered organic superconductor κ-(BEDT-TTF)₂Cu[N(CN)₂]Cl under pressure.It is found that the AMRO amplitude increases with pressure.The AMRO local maxima observed under -- 8 kbar are periodic in scale of tan θ.Analysis based on the generalized two-dimensional Fermi surface model reveals that the orthorhombic symmetry is broken.
