Colossal magnetoresistance without phase separation: Disorder-induced spin glass state and nanometer scale orbital-charge correlation in half doped manganites

R. Mathieu, D. Akahoshi, A. Asamitsu +2

The magnetic and electrical properties of high quality single crystals of $A$-site disordered (solid solution) Ln${}_{0.5}$Ba${}_{0.5}$MnO${}_3$ are investigated near the phase boundary…
