Unusual magneto-elastic forces stabilize the insulating ferromagnetic state of manganites: the La(0.8)Ca(0.2)$MnO(3) case

M. Hennion, F. Moussa, F. Wang +3

The ferromagnetic and insulating state observed in La${}_{1-x}$Ca${}_x$MnO${}_3$, 0.125$<$x$<$0.2, is characterized by structural and magnetic anomalies below T${}_C$, similar to those o…
