Abstract :
Weakly agglomerated crystalline nanoparticles of La1-xSrxMnO3 manganites have been synthesized by solgel method, co-precipitation from nonaqueous solutions and microemulsion technique. Structural and magnetic characteristics of the synthesized particles, as well as their heating efficiency under AC electromagnetic fields are studied. The contributions to AC losses resulted from different heating mechanisms are calculated. The directions to enhance the heating efficiency of various kinds of magnetic nanoparticles are outlined.
