Influence of preparation method on structural, optical and magnetic properties of nickel ferrite nanoparticles

-precipitation (Co-P) routes. The microstructures as well as the magnetic properties of the sintered CSG, SGC and Co-P derived samples were investigated and a critical comparison is presented. 2 Experimental The schematic flowchart of different experimental procedures used for the preparation of NiFe 2 O 4 nanopowders is illustrated in Fig. 1 . The starting materials in all three routes were iron nitrate [(Fe(NO 3 ) 3 ·9H 2 O)] and nickel nitrate [(Ni(NO 3 ) 2 ·6H 2 O)]. All the reagents of analytical grade with a high purity of 99.99% were used as received without

Structural stability, electronic structure and magnetic properties of the new hypothetical half-metallic ferromagnetic full-Heusler alloy CoNiMnSi

excellent HM ferromagnets with large HM gaps. Motivated by the previous studies, our main purpose in this work was to carry out a computational investigation based on first-principles calculations focusing on the structural, mechanical, electronic and magnetic properties of the new hypothetical quaternary CoNiMnSi Heusler alloy. The primary objective was to observe a new instance of HMF in full-Heusler alloys. Our calculation was performed using the full-potential linearized augmented plane wave (FP-LAPW) method, as implemented in the WIEN2k code, in the framework of

Research of magnetic properties of spolic technosols (alcalic/hyperartefactic) on the landfill of industrial waste from nickel production

Abstract

The article presents the results of measurements of magnetic properties of samples spolic technosols (alcalic/hyperartefactic) form the landfill of black nickel mud at Sered’, Slovakia. We measured the dependence of magnetic moment as a function of temperatures (240-340 K) and applied magnetic fields up to 7.2 MA/m (90 kOe). We observed at room temperature the tendency to saturation of magnetic moment. The temperature dependences showed possible ferromagnetic behaviour.

Effect of low oxygen pressure on structural and magnetic properties of quenched SrFe12O19 thin films

Abstract

Strontium hexaferrite thin films have been grown on glass substrates at room temperature in oxygen environment by pulsed laser deposition method. The effect of oxygen pressure (po2) on the structural and magnetic properties has been investigated. The as-deposited films were found to be amorphous in nature. The crystallization of these films was achieved by annealing at a temperature of 850 °C in air. The thickness of the film increased with po2. The film grown at po2 = 0.455 Pa had a clear hexagonal structure. The values of coercivity for the films were found to increase with po2.

Effect of the electrodeposition potential on the magnetic properties of FeCoNi films

Abstract

The effect of electrodeposition potential on the magnetic properties of the FeCoNi films has been reported in this paper. The FeCoNi electrodeposition was carried out from sulfate solution using potentiostatic technique. The obtained FeCoNi films were characterized by X-ray diffractometer (XRD), atomic absorption spectrometer (AAS) and vibrating sample magnetometer (VSM). It has been shown that the electrodeposition potential applied during the synthesis process determines the magnetic characteristics of FeCoNi films. The more negative potential is applied, the higher Ni content is in the FeCoNi alloy. At the same time, Co and Fe showed almost similar trend in which the content decreased with an increase in applied potential. The mean crystallite size of FeCoNi films was ranging from 11 nm to 15 nm. VSM evaluation indicated that the FeCoNi film is a ferromagnetic alloy with magnetic anisotropy. The high saturation magnetization of FeCoNi film was ranging from 86 A·m2/kg to 105 A·m2/kg. The film is a soft magnetic material which was revealed by a very low coercivity value in the range of 1.3 kA/m to 3.7 kA/m. Both the saturation magnetization and coercivity values decreased at a more negative electrodeposition potential.
