Structural and magnetic study of La0.7Sr0.3MnO3 nanoparticles and AC magnetic heating characteristics for hyperthermia applications
TLDR
In this article, structural and magnetic properties and alternating current magnetic heating characteristics of La 0.7 Sr 0.3 MnO 3 nanoparticles with respect to the possible application for magnetic hyperthermia treatments were investigated.Abstract:
We investigated structural and magnetic properties and alternating current magnetic heating characteristics of La 0.7 Sr 0.3 MnO 3 nanoparticles with respect to the possible application for magnetic hyperthermia treatments. Using Rietveld Profile refinement of powder X-ray diffraction data, the hexagonal structure has been observed. The particle sizes varied from 20 to 50 nm as the annealing temperature increases from 700 to 900 °C. The hysteresis loop is not observed and the good fit of Langevin function with magnetization data reveals the superparamagnetic nature at room temperature for all samples. Characteristic magnetic parameters of the particles including saturation magnetization in the temperature range 10–300 K, an effective anisotropy constant and a magnetocrystalline anisotropy constant have been determined. The Specific Absorption Rate for 15 mg/mL sample concentration was measured in alternating magnetic fields of 50–80 Oe at a fixed frequency of 236 kHz. In addition, the intrinsic loss power (ILP) has been calculated from SAR values. It is believed that La 0.7 Sr 0.3 MnO 3 nanoparticles with a high ILP will be useful for the in situ hyperthermia treatment of cancer.read more
