Investigation of Structural Electrical Magnetic and Optical Properties of Substituted Mn Zn Nanoferrites

Abstract

In the present study, transition metal ion (Cu, Cr)-doped Mn-Zn nanoferrites were synthesized by solution combustion method, respectively. All prepared samples were investigated systematically at room temperature by using X- ray diffraction (XRD) and Field Emission Scanning electron microscopy (FESEM) in order to study the structural, morphology and phases respectively. Further optical, magnetic and electrical properties were done by using UV-visible (UV-vis) spectroscopy, vibrating sample magnetometer (VSM), LCR meter and four probe method respectively. Structural study confirms the formation of well-defined cubic structure of Mn-Zn nanoferrites without any introduction of impurity due to addition of dopant ions. Also formation of particles as well as morphology was confirmed in FESEM images. Optical behavior of Mn-Zn nanoferrites enhanced with the addition of dopant. The incorporation of these transition metal ions introduces the soft magnetic behavior. The electrical study provides us the opportunity to tune its conductivity with the help of dopant addition to make it suitable for various electromagnet applications. newline
