Abstract

Ni AlxCrx Fe2-2x O4 ferrite system was prepared using a conventional double sintering ceramic technique.The powders of the oxides and carbonates (Iron, Nickel, Aluminum, and chromium)which form the sample were mixed in molar ratio(X =  0.1 … 0.8 in step 0.1).This research studies the influence Al3+andCr3+ionssubstitutedFe3+ ions in the octahedral sites of spinel ferrite structure.In this work,wenoticed that jump length decreases in octahedral sites with increasing X, while the magnetization of sample increases in the range X 0.6 which corresponds tojump length L 2.928 A0

 

 

حضرنا الفرايت Ni AlxCrx Fe2-2x O4 بالطريقة السيراميكية التقليديةالثنائية التلبيد. وذلك بخلطمساحيق الأكاسيد والكربونات المكوّنة للعينة (أوكسيد الحديد + أوكسيد النيكل + كربونات الألمنيوم والكروم) بنسب موليةمحددة X =0.1… 0.8))بخطوة 0.1.ويهدف هذا البحث إلى دراسة تأثير استبدال شوارد Fe3+بشوارد Cr3+ وAl3+ في المواقع ثمانيةالأوجه في بنية سبينل فرايت.

ولاحظنا في هذا البحث أن طول القفز في المواقع الثمانية تناقص مع زيادة نسب الإضافة X، بينماتزداد شدة التمغنط للعينة المدروسة في المجالX 0.6التي توافق طول قفزقدرهL 2.928 A0.
