摘要：

The effect of a two-way field containing a vertical and transverse AC magnetic field on heating abilities of Fe3O4 is investigated for magnetic nanoparticles with average sizes of 8.8 nm and 13.5 nm. The measurement shows that the heating abilities of our samples are size-dependent and field-dependent. We find that applying a two-way field can strongly increase the heating ability of larger-sized magnetic nanoparticles. That heating ability is different from the one under a single magnetic field. These large-sized Fe3O4 MNPs are thus suitable candidates for hyperthermia under a suitable two-way field. (C) 2011 Elsevier B.V. All rights reserved.
