N2 - The magnetic and transport properties of the Cr-doped manganites [Formula presented] ( [Formula presented]) with the [Formula presented]-type antiferromagnetic structure were investigated. Upon cooling, we find multiple magnetic phase transitions, i.e., paramagnetic, ferromagnetic (FM), antiferromagnetic (AFM), and spin glass in the [Formula presented] sample. The low temperature spin glass state is not a conventional spin glass with randomly oriented magnetic moments but has a reentrant character. The reentrant spin glass behavior accompanied by the anomalous multiple magnetic transitions might be due to the competing interactions between the FM phase and the [Formula presented]-type AFM matrix induced by the random Cr impurity.
