Abstract

Measurements of the proton spin-lattice relaxation rate, T1-1, reveal that the organic insulator copper phthalocyanine Cu(PC) is a highly one-dimensional Heisenberg system. T1-1 diverges as -1/2 down to 11.4 MHz without evidence of cutoff. It was found that J/kB=0.286 K with the ratio J/J6×103, where J and J are the intrachain and interchain exchange interactions, indicating that Cu(PC) is an excellent model one-dimensional Heisenberg magnet.
