摘      要：Nano-magnetic ferrites with composition Mg_(1-x)Zn_(x)Fe_(2)O_(4)(x=0.3,0.4,0.5,0.6,and 0.7)have been prepared by coprecipitation method.X-ray diffraction(XRD)studies showed that the lattice parameter was found to increase from 8.402 to 8.424A with Zn^(2+) ion content from 0.3 to *** transform infrared(FTIR)spectra revealed two prominent peaks corresponding to tetrahedral and octahedral at around 560 and 430 cm^(-1) respectively that confirmed the spinel phase of the *** electron microscopy(TEM)images showed that the particle size was noted to increase from 18 to 24 nm with an increase in Zn content from x=0.3 to *** magnetic properties were studied by vibrating sample magnetometer(VSM)and electron paramagnetic resonance(EPR)which ascertained the superparamagnetic behavior of the samples and contribution of superexchange *** maximum magnetization was found to vary from 23.80 to 32.78 emu/g that increased till x=0.5 and decreased ***,X-ray photoelectron spectroscopy(XPS)was employed to investigate the chemical composition and substantiate their oxidation states.
