Fig. 4: Magnetic phase diagram of Gd6(Mn1−xFex)23.
a Summary of element specific TCs, \({M}_{{Tot}}^{X}\) and \({M}_{{Tot}}^{B}\) as a function of x. The plots of TC(Gd) (empty red circle 
) and TC(Fe) (red cross circle 
) can be divided into three regions: (i) For 0.0 < x ≤ 0.15, bulk TC is determined by Mn sublattice, and TC(Gd) = 273.5 K < bulk TC. (ii) For 0.15 < x ≤ 0.72, the Gd and Fe sublattices show same TC = bulk TC. (iii) For 0.72 < x ≤ 1.0, the Fe moments determine the bulk TC, and TC(Gd) = 273.5 K < bulk TC. b Summary of Mn and Fe magnetic moments (µMn, µFe) as a function of x, showing switching of Mn moments for x ≥ 0.2 plotted with magnetic moments from 3s HAXPES analysis55. Error bars represent standard error (SE).
