Abstract
We investigated electrical and magnetic properties of the electron-doped manganites Ca1-xSmxMnO3 (0<x<0.2). Our results indicate the possibility of phase separation in electron doped manganites. The compounds with x = 0.13-0.15 show unusual difference between zero-field cooled and field-cooled resistivities which are not observed in lower compositions. Our results suggest that electronic phase separation alone is insufficient to understand the origin of the resistivity irreversibilities.
