摘要：

Concave octahedral Mn3O4 microcrystals were synthesized. The magnetic properties of the obtained concave octahedral Mn3O4 microcrystals were investigated from 5 K to 300 K. The blocking temperature was 41.1 K. The Curie-Weiss temperature was 43.5 K, which was higher than that of bulk single-crystal Mn3O4 (42 K).
