Abstract
Reentrant charge ordering (CO) has been evident as a systematic nature in t he bilayered manganites La2-2xSr1+2xMn2O7 (0.45 less than or equal to x les s than or equal to 0.60) at low temperatures. Measurements of physical prop er-ties reveal that the reentrant CO melting (RCOM) is essentially derived by a phase competition between CO and ferromagnetism. Phase separation, alo ng with the RCOM, has been directly observed by means of low-temperature tr ansmission-electron microscopy.
