Abstract

The exchange bias (EB) effect has been observed in magnetic Bi $_{0.9}$ Gd $_{0.1}$ Fe $_{0.9}$ Ti $_{0.1}$ O $_{3}$ nanoparticles. The influence of magnetic field cooling on the exchange bias effect has also been investigated. The magnitude of the exchange bias field ( $H_{E B}$ ) increases with the cooling magnetic field, showing that the strength of the exchange bias effect is tunable by the field cooling. The $H_{E B}$ values are also found to be dependent on the temperature. This magnetically tunable exchange bias obtained at temperatures up to 250 K in Bi $_{0.9}$ Gd $_{0.1}$ Fe $_{0.9}$ Ti $_{0.1}$ O $_{3}$ nanoparticles may be worthwhile for potential applications.
