Ground-State and Local Excitations in Co(PYR)2Cl2
Co(pyr)2Cl2 has been established as a reasonably good representation of a quasi-one-dimensional Ising model by specific heat, susceptibility, and magnetization measurements. The intrachain interaction was found to be ferromagnetic (Jo/k = 10 K). The interchain interactions J’/k amount to approximately two percent of Jo/k, and give rise to a three-dimensional long-range ordered state below T = 3.17 K .
