    Abstract

    We succeeded in observing ferromagnetic (FM) microdomains in the phase-separated state found in Cr-doped (formula presented) by low-temperature Lorentz microscopy. The presence of the FM microdomains with the size of 20–30 nm were found in (formula presented) for (formula presented) 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.
