عنوان مقاله [English]
In this paper, Bi0.85-xLa0.15YxFeO3 BL0.15YxFO, x 0, 0.03, 0.1, 0.15 nanoparticels were synthesized by the tartaric acid modified sol-gel technique. This materials have perovskite structure. In perovskite lattice, such distortions change the B-O-B bond angles and there fore are expected to affect magnetic and electronic properties of this lattice. The crystallographic phase analysis was performed for x 0.1 and x 0.15 with the help of FULLPROF program and showed the crystal structure transition from rhombohederal to the orthorhombic. The results of VSM analysis showed that remnant magnetization and maximum magnetization decreases with increasing the percent of doping.
