Synthesis and the study of magnetic characteristics of nano La1-xSrxFeO3 by co-precipitation method


The goal of this study was the sol-gel synthesis of nanocrystals La1-xSrxFeO3 (x=0.0, 0.1, 0.2, 0.3) and an examination of their magnetic properties. An aqueous solution of ammonia and 5% ammonium carbonate solution were used as precipitating agents. It was established that the crystallization of LaFeO3 is completed at 750◦C (annealing for 1 h). The average diameter of the synthesized particles was 80–100 nm. Investigation of the magnetic properties showed non-monotonic changes of saturation magnetic moment and increase of coercive force with increased Sr content in the sample.
