Abstract
La0.7Sr0.3MnO3 and La0.7Ca0.3MnO3 nanoparticles were synthesized by reactive milling method. Grain size determined from XRD, TEM, and magnetization measurements show an average diameter ⩽18 nm and decreasing with increasing milling time. DC and AC magnetic measurements evidenced an interacting superparamagnetism due to clustering of perovskite nanoferromagnets with spin dynamic time in range of 10−9–10−10 s.
