Abstract

Two-dimensional antiferromagnetic order has been detected in a single crystal of MnTiO₃ by measurements of magnetic susceptibility and by neutron diffraction techniques. Quasielastic magnetic scattering resulting from two-dimensional order was found above the Néel temperature (T_N = 64°K). From 64°K to 56°K the sublattice moment follows a (T_N - T)^β law with β = 0.32 ± 0.01 as in a three-dimensional antiferromagnet. This is contrasted with the result for K₂NiF₄ which is considered to be a typical two-dimensional antiferromagnet.
