“…functions due to the 2p3/2 → continuum transitions. The weight of each valence configuration (4f 13 and 4f 14 ) in the initial valence state is proportional to the peaks surface area S3 and S2. The mean Yb valence was derived from (2S2+3S3)/(S2+S3).…”

We determine the magnetic structures of HoFe6Sn6-type (Immm) YbMn6-yFeySn6 alloys (y = 0.25, 0.50, 0.75 and 1.00) from powder neutron diffraction experiments. The valence state and local magnetism of Yb are investigated using X-ray Near Edge Spectroscopy (XANES) and X-ray Magnetic Circular Dichroism (XMCD) at the Yb L3 edge. The mean Yb valence decreases upon Fe doping (from υ ~ 2.66 down to υ ~ 2.46) and there is no 4f Yb magnetism throughout the series. The Fe for Mnsubstitution leads to change in the spins arrangement of the 3d sublattice by reinforcing antiferromagnetic exchange interactions without significant change in T = Mn/Fe moment magnitude (m ~ 2.35 µB). The ground state of the alloy with y = 0.25 is ferromagnetic whilst Fe richer alloys are helimagnets with wave-vector k = 0, qy, 0. The turn-angle increase upon Fe doping manifests by a mitigation of the Yb L3 dichroic effect, solely due to hybridization between its 5d states and the selfpolarized 3d states of T.

“…to the strong exchange field Hex [11] generated at the Yb site by the neighboring Mn moments. In 1:6:6 phases, Fe is known to promote antiferromagnetic interlayer exchange interactions [12,13]. To better delineate the role of Hex, we aim at investigating the effect of Fe doping in YbMn6Ge6-…”
