Abstract EN
In this research, perovskite-spinel nanocomposites (of the synthsiesed formula (x)(Cuo.3Mn0.7Fe2O4)- (1-x)(La0.9o Bi0.10 FeO3); 0 ≤ x ≤ 1, were prepared using the auto-combustion method.
The fundamental phases of orthorhombic for (La0.9oBi0.10FeO3(LBFO) and the cubic phases for Cuo.3Mn0.7Fe2O4(CMFO) were demonstrated utilizing X-Ray Diffractometry (XRD) analysis..
High-resolution transmission electron microscopy (HRTEM) images reveal nearly spherical nanoparticles for the parents compositions and agglomeratation for nanocomposites.
Magnetic hysteresis loops demonstrate ferromagnetic (FM) behavior for the spinel compound and nanocomposite, where LBFO possesses G-type antiferromagnetic (AFM).
Competition between FM and AFM phases leads to enhancement in magnetic parameters such as saturation magnetization (Ms), remnant magnetization (Mr) and coercivity (Hc).
The magnetic properties at low temperatures show a decrease in the magnetization and coercivity with increasing the temperature while the magnetic exchange bias HEB increased until T=200 K and then, decreased.
The intergranular magnetostatics interactions have promoted along the LBFO and CMFO nanocomposites interfaces which play a decisive role in strain energy, exchange energy, and magnetic anisotropy.
