Abstract
The electron-doped magnetic nanoparticles of Ca1-xYxMnO3 (x = 0, 0.05, 0.10,
0.15, 0.20, and 0.30) manganite with an average particle size of 50 nm are
analyzed and discussed in relation to their bulk counterparts. Nanoparticle
samples show dominant anti-ferromagnetic ordering with a significant increase
of coercivity, with the maximum value of 0.9 T for x = 0. Particle size
reduction in Ca1-xYxMnO3 retains the bulk-like magnetic behavior of samples
having up to 15% of Y3+, with the small ferromagnetic contribution from
disordered surface spins. Suppression of charge ordering state and
enhancement of saturation magnetization were found in samples with higher Y3+
concentration (x = 0.2, 0.3), indicating high ferro-magnetic contribution in
these samples.
