Abstract
We report a new finding on the phase coherence between strongly underdoped superconducting Bi2Sr2CaCu2O8+δ (Bi-2212) grains. Contrary to the expectation based on the linear suppression of the superfluid density at T=0 K with the decreasing hole concentration in the underdoped region, the phase coherence between superconducting grains was remarkably enhanced at a hole concentration (p≃0.08) in the underdoped regime. The likely candidate giving rise to our finding is the phase-disordered superconducting quasiparticles around the antinode of the Fermi surface.
