Temperature dependence of the ferromagnetic resonance (FMR) for MnxCo1−xFe2O4 (0 ≤ x ≤ 1) nanoparticles

Ferromagnetic resonance was used to study the temperature dependence of mixed manganese-cobalt ferrite nanoparticles with a size range between 5 and 42 nm synthesized by the hydrothermal method. Structural characterization was carried out using X-ray diffraction, scanning, and transmission electron microscopy. M(H) curves as a function of the Mn2+ content at 2.5 and 300 K, and FMR in the temperature range of 80 < T < 700 K were used for the...
