The canted ferromagnetism of manganese(II) phthalocyanine (PcMn) was studied by torque and magnetization measurements. The experimental results were interpreted in terms of a two sublattice-four domain model. Below the Curie temperature, the magnetic moments on two sublattices which form ferromagnetic linear chains are aligned nearly along the molecular axes and make an angle about 90° with each other resulting in the canted ferromagnetism. This spin structure gives four kinds of domain as observed in the torque measurement. From the analysis on the basis of the molecular field approximation the large and negative crystalline field parameter, D, was found to be responsible to the spin structure in PcMn.
