|a 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 absorption curves change in a nonlinear manner in coated samples in the temperature range of 230 K ≤ T ≤ 290 K. Such changes indicate the appearance of external stresses between nanoparticles due to the difference in the thermal expansion coefficients of the two materials. © 2022 Author(s).
