Abstract

DC SQUID measurements of the temperature dependence of the magnetic susceptibility of europium oxalate decahydrate (Eu₂(C₂O₄)3 • 10H₂O) suggested that there may be magnetic ordering of this compound between 20 and 30 K. Subsequent Mössbauer spectroscopy measurements at 4 K clearly preclude any ordering even at this low temperature and indicate that the rise in the susceptibility is due to impurities. The conclusion is that, even at 4 K, Eu₃₊ is present in an unordered state.
