Abstract

A magnetic phase transition in the perovskite-type layered structure compound (C₁₈H₃₇NH₃)₂MnCl₄, accompanied by a discontinuity in the weak-field magnetization, was found at 359 K, far above the Neel temperature. Our observations were well explained by the magnetic and the structural orders being coupled via a magnetostructural coupling attributable to the Dzyaloshinsky-Moriya interaction.
