In order to investigate the electronic state of Ce-free and Ce-underdopedhigh-Tc cuprates with the so-called T' structure, we have performedmuon-spin-relaxation (muSR) and specific-heat measurements of Ce-freeT'-La_1.8_Eu_0.2_CuO_4+d_ (T'-LECO) polycrystals and Ce-underdopedT'-Pr_1.3-x_La_0.7_Ce_x_CuO_4+d_ (T'-PLCCO) single crystals with x=0.10. ThemuSR spectra of the reduced superconducting samples of both T'-LECO with Tc=15Kand T'-PLCCO with x=0.10 and Tc=27K have revealed that a short-range magneticorder coexists with the superconductivity in the ground state. The formation ofa short-range magnetic order due to a tiny amount of excess oxygen in thereduced superconducting samples strongly suggest that the Ce-free andCe-underdoped T'-cuprates are regarded as strongly correlated electron systems.
