Crystal and magnetic properties of YbMn 6−y Fe y Sn 6 (y ≤ 1)

Influence of Fe doping on the Yb valence state and the magnetic structures in HoFe6Sn6-type YbMn6−yFeySn6 alloys (y ≤ 1.00)

“…The samples investigated here are those used in Ref. [15] where details about the synthesis procedure can be found. They are almost single-phase with low level (< 5 wt.…”

“…As a result, some Yb-filled hexagonal prisms are only corner-sharing and the kagomé layers are slightly corrugated. In YbMn6-yFeySn6, the cell volume shrinks upon Fe doping as ∆~ 0.144∆ [15]. In YbMn6Sn6, the Mn sublattice is purely ferromagnetic with TC ~ 300 K [17].…”

“…In YbMn6Sn6, the Mn sublattice is purely ferromagnetic with TC ~ 300 K [17]. The partial substitution of Fe for Mn has little influence on the ordering temperature but yields the appearance of an antiferromagnetic-like phase at low temperature [15]. The latter develops upon Fe doping to cover almost the entire ordered temperature range for y = 1.00.…”

“…In the present work, we complete our former study on YbMn6-yFeySn6 (y ≤ 1.00) [15] using powder neutron diffraction as well as X-ray Near Edge Spectroscopy (XANES) and X-ray Magnetic Circular Dichroism (XMCD) measurements at the Yb L3 edge. This work is organized as follows.…”

Pressure influence on the valence and magnetic state of Yb ions in noncentrosymmetric heavy-fermion YbNiC2

“…It is known that the electronic and magnetic properties of Yb strongly depend on the properties of its partner [3,[20][21][22][23][24][25][26][27][28]. In Ref.…”
