Abstract

We investigated differential conductance properties of c-axis microbridges fabricated in La_2−xSr_xCuO₄ (LSCO) single crystals. Periodic conductance peaks were observed in both overdoped and underdoped LSCO samples. We applied a magnetic field parallel to the ab-plane and examined the behaviors of differential conductance properties (DCPs). The DCP of the overdoped sample was little affected by magnetic fields up to 4 T, whereas that of the underdoped sample exhibited strong dependence on the magnetic field.
