Abstract

Weakly agglomerated crystalline nanoparticles of La_1-xSr_xMnO₃ 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.
