Abstract
We report measurements of the magnetic susceptibility and electrical resistivity of the iostructural compounds RE 2Zn 17 (RE=La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu). The composition dependence of the lattice parameter and effective moment indicate that all the RE ions are trivalent except Yb which is divalent. Magnetic order is observed in compounds where RE=Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho and Er. A second transition is seen for RE=Pr, Ho, Sm and Tb. Superzone boundary effects are observed in the electrical resistivity of these four alloys as well as in Er 2Zn 17. Resistivity measurements reveal concentrated Kondo behavior (or 4f instability) of Ce in Ce 2Zn 17.
