The La0.7Ce0.3MnO3+ d compounds and epitaxial thin films were fabricated by the solid state reaction and the pulse laser deposition methods, respectively. The XRD patterns, the temperature dependence of resistivity, the temperature dependence of the magnetization and the temperature dependence of the heat specific of these samples were measured. We thought the sample La0.7Ce0.3MnO3+ d was electron doped system. Both the bulk sample and the thi n film sample show paramagnetic-ferromagnetic transition and metal-insulator transition phenomena. In addition, both them display a prominent giant magnetoresistance (CMR) around the Curie temperature. However, the temperature of paramagnetic-ferromagnetic transition and CMR between them was different..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
