Abstract: The magnetic characteristics of a nanocrystalline material based on bismuth ferrite Bi$_2$Fe$_4$O$_9$ with 60 $\pm$ 3 nm crystallites were studied. The obtained material demonstrates unusual magnetic properties, which are manifested in a significant increase in the value of magnetization in comparison with the data known from other works.

Keywords: nanocrystals, bismuth ferrite, mullite, magnetic properties.
