Magnetic MgxCoyZn(1-x-y)Fe2O4 nanoparticles were successfully prepared by the rapid combustion approach, and SEM, XRD, VSM, EDX, FTIR techniques applied for their characterization. The influence of element ratios (Mg2+, Co2+, Zn2+) in magnetic on properties was explored. To acquire a larger specific surface area better adsorption methyl blue (MB), Mg0.4Co0.5Zn0.1Fe2O4 calcined at 400°C 2 h with...

در این مقاله حل دقیق ارتعاش برون صفحه‌ای نانو ورق‌های مستطیلی نسبتاً ضخیم براساس تئوری غیر‌محلی تغییر شکل برشی سینوسی اصلاح شده با نظر گرفتن شرایط مرزی لوی ارائه است. هدف اصلی تحقیق بررسی اثر مقیاس کوچک بر پارامترهای فرکانسی می‌باشد. برای توصیف تأثیرات خارج از صفحه‌ی ورق غیر محلی ارینگن استفاده شده. مشتمل شش حالت مختلف شامل دو ضلع موازی دارای تکیه‌گاه ‌ساده و اضلاع دیگر ترکیبی ساده، گیردار آزاد ...

Magnetic insulators are important materials for a range of next-generation memory and spintronic applications. Structural constraints in this class devices generally require clean heterointerface that allows effective magnetic coupling between the insulating layer conducting layer. However, there relatively few examples can be synthesized with surface qualities would allow these smooth interfac...


 The soft chemical method was adopted to prepare of cobalt-substituted nickel-zinc ferrites (Ni0.95-x Zn0.05COx Fe2O4 for x = 0.01, 0.02 and 0.03). We have recently studied their structural, morphological, magnetic properties, initial permeability, dielectric constant. They were found be with cubic ferromagnetic spinel structure, the morphology which is suitable high-density recording med...
