Fig. 5From: Iron-Doped (La,Sr)MnO3 Manganites as Promising Mediators of Self-Controlled Magnetic NanohyperthermiaMagnetization of La0.77Sr0.23Mn1 − y Fe y O3 nanoparticles vs magnetic field at T = 293 and 303 K. Data for y = 0.02, 0.06, and 0.1 are omitted for clarity. An approximation of experimental data by Langevin function is shown in the inset Back to article page
