    Abstract

    The 1H nuclear spin-lattice relaxation behavior was characterized in the perovskite-type layered structure quasi-two-dimensional Heisenberg paramagnets, (CnH2n+1NH3) 2MnCl4,with different chain lengths (n = 8, 10, and 12). In contrast to the case of the short-chain compound with n = 8, the nuclear spin diffusion to the electron spin system alone is not able to fully account for the spin-lattice relaxation in the compounds with longer chain lengths. Our results are discussed in light of the nuclear magnetic relaxation by the regularly distributed dense paramagnetic ions.
