摘要

In the low doping range of x from 0.01 to 0.06 in La_(2-x)Sr_xCuO_4, we observed two electron paramagnetic resonance (EPR) signals: a narrow and a broad one. The narrow line is ascribed to metallic regions in the material, and its intensity increases exponentially upon cooling below ～ 150 K. The activation energy deduced Δ = 460(50) K is nearly the same as that found in the doped superconducting regime by Raman and neutron scattering. Obtained results provide evidence of the microscopic phase separation and two type of quasiparticles in lightly doped La_(2-x)Sr_xCuO_4.
