Sol-Gel Synthesis of Ce_4-x Sr_1+x Fe_5-x Zn _x O_14+δ [0 ≤ x ≤ 0.45] Superparamagnetic Oxide Systems and Its Magnetic, Dielectric, and Drug Delivery Properties.

ABSTRACT: In this work, we have successfully synthesized superparamagnetic nanocomposites, Ce_4-x Sr_1+x Fe_5-x Zn _x O_14+δ (0 ≤ x ≤ 0.45) (CSFZ) (TA1-TA4: x = 0, 0.15, 0.30, and 0.45) via the Nitrate-citrate sol-gel method. X-ray diffraction studies show the formation of single-phase nanocomposites (NCs) and the average crystallite size is found to be 18 nm. Energy-dispersive X-ray spectroscopy analysis supports the formation of the desired product with the expected composition. The scanning electron microscopy image shows that the prepared samples are in spherical shape and highly porous in nature. Most of the particle sizes present in the image are in the range of 5-20 nm. The optical studies show an inte
