Figure 3
False-colour plots of ∂M/∂H interpolated from the isothermal magnetization curves upon a field change from 9 T to −9 T for (top) Mn5Si3 measured with 3 K temperature steps and (bottom) Mn3Fe2Si3 measured with 5 K temperature steps with field (left) ∥ and (right) ⊥ [001]. Note the different colour ranges of the top and bottom panels. Labels annotate the different features as discussed in the text. |
