Abstract

We have studied magnetostructural phase transitions in the perovskite-type layered structure compound (C₁₈H₃₇NH₃)₂ MnCl₄ by means of electron paramagnetic resonance (EPR) and superconducting quantum interference device (SQUID) measurements. Distinct slopes were observed in the linear temperature dependences of the Mn⁺⁺ EPR linewidth in the low and high temperature phases. Besides, linewidth anomalies at the transition temperatures sensitively reflect the magnetic changes arising from the MnCl₆ octahedra.
