a−g Temperature dependences of normalized zero-field-cooled magnetization, Mzfc(T)/Ms, for Co/Fe(tFe) and Fe/Co(tCo) MNPs: open circles—experimental data obtained in a field of 50 Oe; red solid lines—fitted curves with the use of Formula (2). Dotted rectangles show regions where the maximal correspondence between experimental and fitted curves was targeted. h Dependence of blocking temperature Tb on the thickness of shells
