Low-temperature ferromagnetic resonance in bare and SiO2coated La0.775Sr0.225MnO3nanoparticles

Low-temperature ferromagnetic resonance in bare and SiO2coated La0.775Sr0.225MnO3nanoparticles

La0.775Sr0.225MnO3 nanoparticles were synthesized by sol-gel method with heat treatment at T = 1073 K and covered with silica shells of various thicknesses. Analysis of their experimental ferromagnetic resonance spectra was carried out in the temperature range of 77-290 K. The linewidth of absorptio...
