Abstract:

Using the solid-state pyrolysis of metal-phthalocyanines (NiPc and CuPc), carbon-coated ferromagnetic Ni1-xCux (0 < x < 0.5) nanoparticles have been synthesized. The structure, composition and morphology of samples were investigated by means of scanning electron microscopy, energy-dispersive X-ray analysis, and powder X-ray diffraction. It is shown that the mean sizes of nanoparticles are varied from 30–40 nm to 350–400 nm depending on the pyrolysis conditions, and the thickness of carbon coating is about 10–20 nm. From X-band ferromagnetic resonance spectra it is obtained that the Curie temperature of nanoalloys can be varied in a wide range (from –150°C to 60°C) depending on the concentration of diamagnetic Cu atoms. The prepared samples can be used for self-regulating magnetic hyperthermia in oncology.
