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