摘要：
In the present work, CoMnO3, Co3O4 and Mn2O3 powders were prepared by using a simple hydrothermal method, and the urea and polyvinyl alcohol (PVA) were served as the precipitator and surface active agent, respectively. The CoMnO3 and Mn2O3 exhibit the same spindle-like structure with the size of several micrometers, while the Mn2O3 displays the nanosheet morphology, the as-prepared materials are all high degree of crystallinity. In addition, the magnetic properties discussion indicates that the as-prepared materials exhibit ferromagnetic and antiferromagnetic behaviors at 5 K and 300 K, respectively.
