| This work is devoted to the analysis of the impact of halogen impurities on magnetic properties of the metal-organic framework Fe-MOF-74. Antiferromagnetic and ferromagnetic states have been studied in the guest-free Fe-MOF-74. We have found that this material is ferromagnetic at low temperatures below 4 K. The halogen absorption leads to the decrease of the intrachain exchange interaction between iron atoms and the increase of the interchain exchange. As a results, we observe the increase of the Curie temperature up to 89 K in the Br2 absorbed Fe-MOF-74. |
