Magnetic field induced ferroelectric loop in Bi0.75Sr0.25FeO3−δ
Magnetic field induced ferroelectric loop in Bi0.75Sr0.25FeO3−δ
Magnetic field induced ferroelectric hysteresis loop observed in Bi0.75Sr0.25FeO3−δ is of prime importance. The coexistence of antiferromagnetism and weak ferromagnetism is responsible for the original magnetoelastic and magnetoferroelectric properties. Upon external magnetic field application, the existence of a magnetostrictive effect supports a structural transition toward a homogeneous antiferromagnetic and ferroelectric …
