The Low Temperature Transformation in Ferrites
The general behavior of majrn»!it< (iron ferrite) at its low temperature transformation (ca 1!8°K) is reviewed. One of the properties which undergoes a largr change is the magnetocrystailine snisotropy, which is larger in magnitude and has a lower symmetry below the transformation. The magnetic symmetry axis below the transition tempeiature can be predetermined by cooling a single crystal throu...
متن کاملPreparation of high-permeability NiCuZn ferrite.
Appropriate addition of CuO/V2O5 and the reduction of the granularity of the raw materials particle decrease the sintering temperature of NiZn ferrite from 1200 degrees C to 930 degrees C. Furthermore, the magnetic properties of the NiZn ferrite prepared at low temperature of 930 degrees C is superior to that of the NiZn ferrite prepared by sintering at high temperature of 1200 degrees C becaus...
متن کاملEnhancement of Néel temperature and electrical resistivity of Mn–Ni–Zn ferrites by Gd3+ substitution
Structural, magnetic, and dielectric properties of various Mn0.5Ni0.1Zn0.4Fe2−xGdxO4 sintered at 1200 ◦C were investigated thoroughly. The samples were synthesized by standard solid state reaction technique. The crystal structure was characterized by X-ray diffraction (XRD), which has confirmed the formation of single phase spinel structure. Bulk density, average grain size and initial permeabi...
متن کاملEffect of Sintering Temperature on Structural and Magnetic Properties of Ni0.55Zn0.45Fe2O4 Ferrites
The effect of frequency and sintering temperature on initial permeability of Ni0.55Zn0.45Fe2O4 ferrites have been studied by using an impedance analyzer. The samples were prepared by conventional double sintering ceramic technique using oxide nanoparticles of grain size 30 50 nm. Single phase spinal structure has been confirmed for the prepared samples by X-ray diffraction. As the sintering tem...
متن کاملInvestigation of influences of alloying elements and sintering temperature on the properties of high strength low alloyed sintered steel
Producing parts with high density and improved mechanical properties is one of the most important aims of powder metallurgy process. There are many factors for attaining modified properties in sintered parts but among them controlling type and quantity of alloying elements and manufacturing parameters such as compacting pressure, sintering temperature are the most effective. In this research, t...
