The magnetic behavior of these complexes was measured as a function of magnetic field strength （0-3.98 ~ 106 A/m） at 5 K and as a function of temperature （5-300 K） at a magnetic field strength of 2.39 × 10^6 A/re. Experimental results show that DAPcIPA-Ni^2＋, DAPcIPA-Co^2＋ are soft ferromagnets while DAPcIPA-Fe^2＋ exhibits features of an antiferromagnet.展开更多
