Figure 15: Mössbauer spectra of Fe (64.94%) Ni (25.25%) Mn (9,83%) nanoparticles. (a) Nanoparticles with a core size of 𝐷 = ( 5 - 8 ) nm; singlet, 𝑆 1 = 0 . 0 2 ; oxide doublet, 𝑆 2 = 0.16; two sextets: (I) 𝑆 3 = 0.25, 𝐻 3 = 3 4 . 0  T; 𝑆 4 = 0.13, 𝐻 4 = 2 9 . 5  T; (II) “sagged” line 𝑆 5 = 0.44. (b) Nanoparticles with a core size of D = (10–15) nm; singlet, 𝑆 1 = 0.12; oxide doublet, 𝑆 2 = 0.12; two sextets: (I) 𝑆 3 = 0.24, 𝐻 3 = 3 4 . 5  T; (II) 𝑆 4 = 0.13, 𝐻 4 = 2 9 . 5  T; “sagged” line 𝑆 5 = 0.39.
