MNP heating performances in water for the PT and MHT heating modalities. Temperature elevation profiles for nanospheres (A–C) and nanoflowers (D–F) irradiated with a 1064 nm laser at a power density of 0.3 W cm−2 (A,D), 1 W cm−2 (B,E), and exposed to alternating magnetic fields at 18 mT and 470 kHz (C,F), according to their concentration, ranging from 0.5 to 168 mM of Fe. All the MNPs are studied in their magnetite (full dotted lines) and maghemite (empty dotted lines) forms.
