We succeeded in observing ferromagnetic (FM) microdomains in the phase-separated state found in Cr-doped Nd0.5Ca0.5MnO3 by low-temperature Lorentz microscopy. The presence of the FM microdomains with the size of 20-30 nm were found in Nd0.5Ca0.5Mn1-yCryO3 for y=0.03. In addition, it is clearly shown that the low-temperature phase characterized as the phase-separated state consists of a fine mixture of the two competing ground states, the FM metallic state and the charge/orbital ordered insulator one. Our experimental findings clearly demonstrate the occurrence of microscopic and static phase separation in the Cr-doped manganites.
