Abstract

We have studied phase transitions and nuclear magnetic relaxation associated with phase transitions in the perovskite-type layered structure compound (C18H37NH3)2MnCl 4 by means of 1H nuclear magnetic resonance (NMR). Spin-lattice relaxation was well described by the diffusion limited case, and a strong correlation between the NMR second moment and the spin-lattice relaxation rate, below a high phase transition temperature, provided a clue to its magnetic nature.
