| Description |
We report synthesis of self-assembled Bi2Fe4O9 nanochains by hydrothermal method using Oleic acid as a surfactant which plays an important role in the self-assembled nanochain formation. Temperature dependent dc magnetization study suggests downward shift of the Neel temperature TN -63 K for the particles of size -22 nm while it is reported to be -260 K in the bulk sample. The magnetic hysteresis (M-H) loops offer evidence of weak ferromagnetism across the entire temperature range 10-300 K. Exchange coupling across the interface between coexisting ferromagnetic and antiferromagnetic orders gives rise to a small amount of exchange bias at low temperature. The sample also exhibits substantial magnetoelectric multiferroic coupling at room temperature with-77% suppression of ferroelectric polar-ization under 10 kOe magnetic field. (c) 2021 Elsevier B.V.
