摘要

A magnetic study has been carried out in the temperature range 1.2-25 K and magnetic field range 0 to 50 kOe on single crystals of manganese (II) phthalocyanine. At higher temperatures the magnetic properties of manganese (II) phthalocyanine exhibit chain-like characteristics which may be understood in terms of ferromagnetic Heisenberg intrachain exchange of S = 3/2 ions with a weak antiferromagnetic interchain interaction. In the ordered state, Tc, = 8.3 K, MnPc is a canted ferromagnet with easy axes of magnetization being along X1 and X3 directions. A zero-field splitting of the single ion 4A2 state of the manganese (II) ion gives rise to canted ferromagnetism which does not show complete saturation at the high field range of these experiments (50 kOe). The spin structure of manganese (II) phthalocyanine at low temperature is discussed. (Author)
