We report on the variations of magnetic properties of nanosized manganites both of the phase La0.63Ca0.37MnO3 and La0.25Ca0.75MnO3. Magnetic characterizations indicate that the effect of nanostructuration is to depress the magnetic behaviour that is predominantly observed in the “bulk” sample. At the smallest grain size, the behaviour of nanostructured La0.63Ca0.37MnO3 and La0.25Ca0.75MnO3 tends to be very similar in spite of the great difference observed in the bulk compounds in the different part of the phase diagram.

Abstract

We report on the variations of magnetic properties of nanosized manganites both of the phase La0.63Ca0.37MnO3 and La0.25Ca0.75MnO3. Magnetic characterizations indicate that the effect of nanostructuration is to depress the magnetic behaviour that is predominantly observed in the “bulk” sample. At the smallest grain size, the behaviour of nanostructured La0.63Ca0.37MnO3 and La0.25Ca0.75MnO3 tends to be very similar in spite of the great difference observed in the bulk compounds in the different part of the phase diagram.
