摘要：

The magnetic susceptibilities of powdered samples of Me4NCuCl3 (TMCuC) and [(CH3)NH3]Cu23Cl7 (TTMCuC) have been measured. Both compounds behave like one-dimensional S=12 Heisenberg ferromagnets which are weakly coupled antiferromagnetically to adjacent chains. For TMCuC, we obtained Jk=30 K with |J′|̂0.003 K; the ratio |J′J| is the lowest yet found for a ferromagnetic S=12 chain. For TTMCuC, we obtained JFMk=50 K, with |J′JFM|̂10-4, and JAFMk=-10 K for the antiferromagnetic chains also present. © 1979 The American Physical Society.
