چکیده

در این پژوهش، پودر فریت Mn0.5Zn0.5Fe2O4 به روش ساخت احتراقی گلیسین-نیترات، در نسبت¬های مختلفی از گلیسین به نیترات تهیه شد. ارزیابی¬های فازی به کمک روش پراش پرتو ایکس نشان داد که فاز فریت منگنز- روی با ساختار بلوری اسپینل به صورت موفقیت آمیزی در تمامی نمونه¬ها ایجاد شده است. خصوصیات مغناطیسی به کمک مغناطش¬سنج نمونۀ مرتعش تعیین شد. مغناطش اشباع در محدودۀ emu/g 3/63¬¬- 5/59 برای نمونه¬های تولید شده مشاهده گشت. ویژگی¬های دی¬الکتریک و الکترومغناطیس به کمک دستگاه LCR-meter ارزیابی شد. نمونۀ تولید شده در کمترین نسبت سوخت به نیترات دارای کمترین تلفات مغناطیسی و بیشترین نفوذ پذیری مغناطیسی است. طیف نگاری امپدانس تنها حضور یک نیم دایره را نشان داده که بیانگر اثر غالب مرزدانه در رفتار مواد مورد مطالعه است.
