Magnetic susceptibility and specific heat measurements have been performed on two-dimensional spin systems (M2+Cl)LaNb2O7 (M = Mn (S = 5/2), Cr (S = 2), Co (S = 3/2)), prepared via a topotactic ion-exchange reaction. All three compounds establish antiferromagnetic order at TN 53 K, 61 K and 52 K, respectively for M Mn, Co, Cr. Together with TN 78 K for M Fe (S = 2), this result indicates that the T N is not simply scaled by the magnitude of spin. In particular, the presence of strong spin-orbit interactions is suggested for (CoCl)LaNb 2O7. © 2011 Published under licence by IOP Publishing Ltd.
