摘要：

We report measurements of the magnetic susceptibility and electrical resistivity of the isostructural compounds RE//2Zn//1//7 (RE equals 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 equals Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho and Er. A second transition is seen for RE equals Pr, Ho, Sm and Tb. Superzone boundary effects are observed in the electrical resistivity of these four alloys as well as in Er//2Zn//1//7. Resistivity measurements reveal concentrated Kondo behavior (or 4f instability) of Ce in Ce//2Zn//1//7.
