外文摘要：We report a systematic study on layered metal SrCu4-xP2 single crystals via transport,magnetization,thermodynamic measurements and structural characterization.We find that the crystals show large linear magnetoresistance without any sign of saturation with a magnetic field up to 30 T.We also observe a phase transition with significant anomalies in resistivity and heat capacity at Tp～140 K.Thermal expansion measurement reveals a subtle lattice parameter variation near Tp,i.e.,△Lc/Lc～0.062％.The structural characterization confines that there is no structure transition below and above Tp.All these results suggest that the nonmagnetic transition of SrCu4-xP2 could be associated with structural distortion.
