| 520 | 3 | |a We have employed the highly sensitive electron magnetic resonance technique complimented by magnetization measurements to study the impact of size reduction on the magnetic ordering in nanosized Sm1−x Ca x MnO3 (x=0.35, 0.65 and 0.92). In the bulk form, x=0.35 sample shows a charge ordering transition at 235K followed by a mixed magnetic phase, the sample with x=0.65 exhibits charge order below 275K and shows an antiferromagnetic insulator phase below 135K while that with x=0.92 has a ferromagnetic-cluster glass ground state. Thus, a comparative study of magnetic ground states of bulk and nanoparticles (diameter ~25nm) enables us to investigate size-induced effects on different types of magnetic ordering. It is seen that in the bulk samples the temperature dependences of the EPR parameters are quite different from each other. This difference diminishes for the nanosamples where all the three samples show qualitatively similar behavior. The magnetization measurements corroborate this conclusion. | |
