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.
