Ca3Co2O6 is a rare example of a material where ferromagnetic 1D Ising spin chains are coupled through a much weaker antiferromagnetic exchange on a triangular lattice.

Low-temperature measurements of magnetization and specific heat, and neutron scattering studies have been used to investigate the magnetic properties of this material.

Immediately below TN, Ca3Co2O6 is shown to order with a modulated partially disordered antiferromagnetic structure. At lower temperature, Ca3Co2O6 undergoes an unusual slow magnetic order-order transition.
