Magnetic Properties of Nano Zinc Ferrite by VSM

Investigating the effect of transition metal ion substitution in nano zinc ferrite and its magnetic properties

Abstract

In the present investigation, studying the effect of transition metal ions substitution in tuning magnetic and dielectric properties of the synthesized materials are the main tasks. A literature review on ferrite samples provides the information about the chronological developments in lower temperature preparation methods, ecofriendly approaches, easily scalable to industry requirements and forecasting the suitability of these samples for the possible applications. The important scientific information findings were reported on transition metals or the rare earth elements doped mixed ferrites. In the present research, undoped and transition metals like Cr3+, Ni2+ and Cu2+ doped ZFs have been chosen to synthesize by three wet chemical methods such as solution combustion (SCS) with ODH as fuel, plant latex mediated combustion or green combustion synthesis (GCS) and hydrothermal (HYDS) routes. In GCS method, the extract from fresh leaves of Mimosa pudica (MP) was selected as a fuel for the preparation of ZFs. The synthesized materials were characterized by advanced materials characterization tools such as XRD, SEM, TEM, FTIR, PCS, UV-Visible spectroscopy, PL, XPS and TGDSC analysis. To know the magnetic interactions in the prepared samples, the magnetic measurements were carried out at room temperature (RT) (for all samples) and below RT (for only undoped ZFs) using vibrating sample magnetometer, VSM 7410.
