A Review on Synthesis and Characterizations of Mixed Nickel-Zinc Ferrites

E-effect in Nickel-zinc Ferrites

A study of the dependence of elastic behaviour of polycrystalline mixed Ni-Zn ferrites of different compositions on temperature and magnetic field (AE-effect) has been made using a ultrasonic method. The variation of Young's modulus with temperature follows Wachtman's equation. The dependence of the Young's modulus on magnetic field is explained using a theoretical model suggesteds by Lewis and...

Synthesis and Characterization of Mixed Ferrites

In this work we prepare nanocrystalline mixed ferrites by equilibrated low entropy routes with generic formula of MnxNi1-xFe2O4. Two series of samples have been prepared where “x” varies as 0.0, 0.1, 0.2, 0.3, 0.4 and 0.5 the samples have been prepared by chemical co-precipitation route. For the first calculated amount of salts of Mn, Fe and Ni were dissolved in deionized water and stirred for ...

Plasma Synthesis of Facetted Nickel nano-Ferrites with Controlled Stoichiometry

Synthesis and Characterization of Nickel Zinc Ferrite Nanoparticles

In this research nickel zinc ferrite nanoparticles with composition of Ni1-xZnxFe2O4 (where x=0, 0.3, 0.7, 1) were synthesized by a sol-gel method at 600 °C for 5 hours. The structure of nanoparticles was studied using X-ray diffraction pattern. The lattice parameter of ferrite nanoparticles was calculated and indicates lattice constant of nanoparticl...

reflections on taught courses of the iranian ma program in english translation: a mixed-methods study

the issue of curriculum and syllabus evaluation and revision has been in center of attention right from when curriculum came into attention of educational institutions. thus everywhere in the world in educational institutions curricula and syllabi are evaluated and revised based on the goals, the needs, existing content, etc.. in iran any curriculum is designed in a committee of specialists and...
