Abstract
In this paper, we investigated the electrical and magnetic properties of electron-doped manganite Y 0.4Ca0.6MnO3 with a relatively small average cationic radius 〈rA〉. The small 〈rA〉 of the present system results in a short-range antiferromagnetic charge-ordering (AFM-CO) state in the manganite. With the decrease of temperature, a ferromagnetic super-exchange interaction begins to establish itself between the remaining disordered Mn ions after the formation of the short-range CO state. Then, a reentrant cluster-glass state originates from the frustration between the FM order in the clusters and the AFM interactions present in the background matrix.
