- •
Griffiths singularity rather than superparamagnetism occurs in La0.5Sr0.5MnO3 nanoparticals.
- •
The sample’s size reduced to nanoscale results in the short-range ferromagnetic interaction.
- •
The core-shell model is used to understand the formation of Griffiths phase in nanometer La0.5Sr0.5MnO3.
