We have investigated the crystal and magnetic properties of the new Yb1-xScxMn6Sn6 compounds (0.00 ≤ x ≤ 1.00). X-ray diffraction experiments show that all samples are isotypic with HfFe6Ge6 and the lattice constants shrink upon increasing the Sc

International audience; Previous experimental and theoretical studies revealed that carbon insertion into the RCrSi compounds drastically affects the magnetic behavior, since chromium does not carry any magnetic moment in RCrSiC (R = Y, La-Sm, Gd-Er)

In the Er–Ge system, the compostion range ErGe2 to Er2Ge3 has been investigated. Eight samples were produced by arc melting of the elements, and analyzed using X-ray powder diffraction. Nine crystal structures were found to be present in the sample
