Dopant-Induced Modulation of Structural and Magnetic Properties in Strontium Ferrite Perovskite Nanomaterials

· Published (2026) on 22 Jan, 2026

This research centres on enhancing the magnetic properties of Europium (Eu) doped Strontium Ferrite (SrFeO3) nanomaterials, synthesized successfully using the solution combustion method. The study explores doping concentrations of x = 0.0, 0.5, and 1.0 and their effects on the structural, morphological, and magnetic characteristics. Techniques such as X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), and a Superconducting Quantum Interference Device (SQUID) magnetometer were employed. XRD analysis shows a reduction in particle size as the Eu dopant concentration increases, while FESEM images reveal uniformly formed nanoparticles with notable agglomeration. Magnetic properties were investigated through temperature and field-dependent magnetization measurements. The field dependence of magnetization at both 5 K and 300 K indicates ferromagnetic behaviour across all samples, with the higher Eu doping concentrations resulting in enhanced magnetic moments. These findings suggest that Eu-doped SrFeO3 nanomaterials hold great promise for applications in spintronics, sensors, and microwave-absorbing devices.
