摘要：
Magnesium nano ferrite substituted with Yttrium and Samarium is synthesized by Sol Gel Auto Combustion method by optimising the sintering temperature and its duration to achieve pure Spinel Phase without any impurity. Particle size obtained from XRD and TEM are in close agreement with each other. Saturation magnetization of Mg-nanoferrite is moderate at room temperature which decreases by substitution of Y &Sm. Magnetic results are further authenticated by Mossbauer Spectroscopic analysis. Experimental results are explained on the basis of existing theories and Models. Magnesium ferrite (substituted with Y &Sm) is chosen because of its potential application in biomedical fields e.g, hyperthermia treatment, drug delivery and even for antibacterial activity.
