The magnetic behavior of Li2MO3 (M = Mn, Ru and Ir) and Li2(Mn1-xRux)O3

The present study summarizes magnetic and Mossbauer measurements on ceramic Li2MO3 M = Mn. Ru and Ir and the mixed Li-2(Mn1-xRux)O-3 materials which show many of the features reflecting to antiferromagnetic ordering or to the existence of paramagnetic states. Li2ArO3 and Li2RuO3 are paramagnetic down to 5K. Li-2(Mn1-xRux)O-3 compounds are antiferromagnetically ordered at T-N = 48 K for x = 0. T-N decreases as the Ru content increases and, for x = 0.8, T-N = 34 K. (C) 2002 Elsevier Science B.V. All rights reserved.
