Abstract

Superparamagnetic nanoparticles of the spinel ferrite four-element system Mn1-xZnx[Fe2-yLy]O4 (where L:Gd3+, La3+, Ce3+, Eu3+, Dy3+, Er3+,Yb3+) were synthesized by the co-precipitation method. The magnetic moments of the 10 nm diameter nanoparticles were comparable to the ones of Fe3O4 nanoparticles. A comparatively low TC (∼52-72 °C) was observed for some of the compositions. The heating mechanism of the superparamagnetic particles in the AC magnetic field at radiofrequency range is discussed and especially the absence of the hysteresis loop in the M-H curve at room temperature. One possible explanation-spontaneous particle agglomeration-was experimentally verified. © 2006 Elsevier B.V. All rights reserved.
