Abstract
The layered compound NbS 2 can be intercalated with Eu, Yb and Sr from liquid ammonia solution at low temperatures. The intercalated species are predominantly divalent ions and produce an expansion in c axis of ∼ 3A. Eu x (NH 3) y NbS 2 (x ≥ y) compounds with x ≳ 0.4 order ferromagnetically below 8°K. Diamagnetic intercalated species lower the superconducting transition temperature of pure NbS 2 whereas paramagnetic species completely destroy the effect. High temperature reactions of Eu with NbS 2 always produce ferromagnetic EuS as an impurity phase and obscure the inherent low temperature properties of Eu intercalated NbS 2.
