Abstract
⺠Core/shell structure with (α-Fe, Fe-B) core and γ-Fe2O3 shell is synthesized. ⺠Diameter of the core is 20 nm and the shell is 7 nm thick. ⺠The role of the core and the shell in the magnetic properties is determined. ⺠The observed blocking temperature TB=30 K is associated with the γ-Fe2O3 shell. ⺠Size dependence is used to explain the observed absence of exchange bias.
